The images below show how to do this on a CONSULT III +, which is Nissan’s dealer-level programming software.

Once you have your TCM part number, check to see whether there is a programming update on Nissan TechInfo

1. Go to https://www.nissan-techinfo.com/ecm07.aspx and enter 30136 in the first ECU part number search box
   
2. Enter the next 5 characters of the ECU part number and click on the Nissan dropdown in ALL CAPS
   
3. Compare the ECU ID to see if there is an update. If you have the current version of ECU software Nissan will not offer a configuration.
   
   1. In order to update the ECU file, you need a subscription to Nissan’s programming software (NERS or Consult III Plus). If you have this software you can download the calibration file from Nissan for $30 and reflash the TCM.
   2. If you do not have the software and cannot hire a programmer with the software, Nissan dealerships will perform the reflash for between $100 – $300.
   3. The DrewTech RAP Kit is also capable of reflashing the TCM on all Nissan models except for the CVT8 that comes with a programming CD (JF016E / RE0F10D in the 2013 and newer Altima and 2014 and newer Rogue)

The CVT oil warmer/cooler has two closed loops to exchange heat between the CVT and the engine.  After starting the vehicle, the engine helps warm the CVT fluid to operating temperature.  During extended operation, the exchange provides a cooling effect as heat from the CVT is exchanged into the engine coolant.

To prevent the CVT from overheating, inspect the engine coolant and replace the engine coolant if it is degraded.  Per the Nissan service manual engine coolant must be replaced at 105,000 miles or 84 months, whichever comes earlier.  Make sure the engine coolant lines are not obstructed and coolant can freely flow into the CVT warmer/cooler.  It is also important to inspect the engine air filter and replace it if dirty or obstructed.  Excess engine temperature will overheat the CVT fluid and may cause premature failure.

CVT Warmer/Cooler Flushing

Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the radiator must be inspected and cleaned.

Metal debris and friction material, if present, can be trapped or become deposit in the CVT fluid cooler. This debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid. In either case, malfunction of the newly serviced CVT may occur.

Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE

1. Position an oil pan under the transaxle’s inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the steel cooler tubes or bypass valve.
4. Allow any CVT fluid that remains in the cooler hoses to drain into the oil pan.
5. Insert the extension adapter hose of a can of Transmission Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler outlet hose.
6. Hold the hose and can as high as possible and spray Transmission Cooler Cleaner in a continuous stream into the cooler outlet hose until CVT fluid flows out of the cooler inlet hose for 5 seconds.
7. Insert the tip of an air gun into the end of the cooler outlet ho
8. Wrap a shop rag around the air gun tip and end of the cooler outlet hose.
9. Blow compressed air regulated to 5 to 9 kg/cm2 (70 to 130 psi) through the cooler outlet hose for 10 seconds to force out any remaining CVT fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the CVT fluid cooler steel lines to the transaxle.
12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the transaxle by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.
14. Blow compressed air regulated to 5 to 9 kg/cm2 (70 to 130 psi) through each steel line from the cooler side back toward the transaxle for 10 seconds to force out any remaining CVT fluid.
15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.

CVT FLUID

• Approximate capacity is 10.2 liters (10 ¼ quarts)
• Berkeley Standard’s reman CVT will already contain approx 3 quarts from the testing machine
• Use only Nissan NS-2 or NS-2 rated CVT fluid
• Use the CVT fluid dipstick to determine the correct fluid level
• Fill CVT fluid from CVT fluid charging pipe to the specified level on the CVT fluid dipstick.
• Adjust CVT fluid level temperature is 50° to 80°C (122° to 176°F). The vehicle needs to warm up for approximately 10 minutes of idle or light driving
• If fluid level is too high, drain the excess fluid from the drain plug on the oil pan
• The CVT fluid should be inspected every 30,000 miles and replaced if burnt, contaminated, or otherwise degraded. Replace CVT fluid with NS-2 rated fluid only.
• NOTE: The fluid change interval for the JF010E CVT is every 60,000 miles. If the vehicle has been driven over 60,000 miles on a Berkeley Standard CVT, maintenance records showing proof of fluid change(s) at 60,000 mile or earlier intervals must be provided in order to ensure warranty coverage.

NOTE: Nissan NS-3 is NOT interchangable with NS-2.  The use of the incorrect fluid will lead to premature wear and overheating of the CVT and will invalidate the warranty coverage.

Filling CVT Fluid
1. Warm up CVT fluid by letting the engine run approx 10 minutes.

2. Refill with new CVT fluid at CVT fluid charging pipe with the engine running at idle speed.
3. Refill until new CVT fluid at the proper level according to the CVT filler tube dipstick

CAUTION: Use genuine NISSAN CVT fluid NS-2.

4. Delete CVT fluid deterioration date with scan tool after changing CVT fluid.
5. Check fluid level and condition.

TCM Initialization Procedure

1. Set the parking brake with the selector lever in “P” (Park).
2. Connect scan tool to the vehicle and turn the ignition ON (engine OFF – not running).
3. Navigate the scan tool to find the TCM Part number
4. Select the TCM part number (P/N) and Calibration Data, and then print and save a copy.
5. Perform the initialization (EEPROM erase) procedure as follows:
6. Select Transmission Self Diagnostic Results.
7. Press and hold the brake pedal.
8. Shift the selector lever to “R” (Reverse).
9. Press and hold the accelerator pedal down about one-third, but no more than halfway.

• The purpose of this step is to get both the wide open throttle and closed throttle position signals to read “OFF” at the same time.

1. Press Erase.

IMPORTANT: During the next step, observe the shift selector position display.

1. Shift the selector lever to “P” (Park).

• If there is a delay with “P” to illuminate, EEPROM has successfully erased.
• If there is no delay, EEPROM has not erased. Perform Step 5 again.

TCM Reprogramming

The vehicle does not require programming unless the TCM software is affected by a service bulletin. To check the TCM software see instructions below:

First, find TCM Part Number with Scan Tool.  The TCM hardware is a computer chip with identical hardware and the part number represents the software the TCM is programmed with.  The TCM part number will start with 31036-XXXX.

If the TCM part number is any of the ones on the table below, the TCM is affected by a service bulletin needs to be reprogrammed with updated software.  This can be done either with a Consult 3+ scanner and programmer (available at Nissan dealerships), or with the RAP Kit by Drew Technologies.

NOTE: The JF010E transmission or valve body does not come with a programming CD.

NOTE: If there are any diagnostic trouble codes (DTC) the transmission may not program.  Clear all DTCs before proceeding with programming.  If there are persistent DTCs, these must be addressed and cleared before programming can proceed.

CURRENT TCM PART NUMBER 31036 – XXXXX

TEST DRIVE AND TRANSMISSION CALIBRATION

After the transmission has been installed use a scan tool to verify the vehicle does not have any diagnostic trouble codes.  If there are codes from the previous transmission, clear them with a scan tool and check if they return.  When the vehicle does not have any codes, clear the TCM memory, self-learning data, and fluid degradation data. Test drive the vehicle for an additional 15 – 20 minutes to allow the TCM to self-calibrate.  Do not test drive the vehicle if it has any DTCs.

The test drive should cover a range of speeds in both forward and reverse. The vehicle may shift abnormally at the beginning of the test drive but should normalize in 20 minutes or less.  If the MIL / check engine light illuminates during the test drive, do not continue driving.

Re-scan the vehicle after the test drive to ensure there are no DTCs.

Pre-installation inspection

Before the transmission is installed check to make sure the JATCO stamp code on the top of the transmission matches the core.  Inspect the transmission for any differences between the core, as well as for any signs of damage or leaking fluid.  If the transmission is different from the core or shows any signs of leaks or visible damage, do not install it.

NOTE: The transmission does not ship with a range sensor (PNP switch).  It is acceptable to reuse the range sensor from the core if it is undamaged.

CVT Warmer/Cooler Flushing

Metal debris and friction material may become trapped in the radiator, cooling hoses, bypass valve or external CVT fluid cooler. This debris can contaminate the newly serviced transmission, control valve or torque converter. In severe cases this debris can block or restrict flow and may cause damage to the newly serviced CVT.  When a CVT, control valve, or torque converter is replaced, the CVT transmission fluid cooler must be flushed.

The CVT oil warmer/cooler has two closed loops to exchange heat between the CVT and the engine.  After starting the vehicle, the engine helps warm the CVT fluid to operating temperature.  During extended operation, the exchange provides a cooling effect as heat from the CVT is exchanged into the engine coolant.

To prevent the CVT from overheating, inspect the engine coolant and replace the engine coolant if it is degraded.  Per the Nissan service manual engine coolant must be replaced at 105,000 miles or 84 months, whichever comes earlier.  Make sure the engine coolant lines are not obstructed and coolant can freely flow into the CVT warmer/cooler.  It is also important to inspect the engine air filter and replace it if dirty or obstructed.  Excess engine temperature will overheat the CVT fluid and may cause premature failure.

The CVT fluid should also be inspected every 30,000 miles and replaced if burnt, contaminated, or otherwise degraded.  Replace CVT fluid with NS-3 rated fluid only.

Flushing Radiator based CVT Transmission Fluid Cooler

IMPORTANT: the CVT fluid cooler hoses will be flushed in both directions in the following procedure.

1. Place the vehicle on a lift.
2. Place an oil drain pan under the CVT Warmer.
3. Disconnect the CVT fluid cooler inlet and outlet rubber hoses from the CVT Fluid warmer and discard spring clamps.
   NOTE: If rubber material from a cooler hose remains on the steel tube or fitting, replace the rubber hose and clean steel tube.
4. Allow any transmission fluid that remains in the CVT fluid cooler hoses to drain into the oil drain pan. NOTE: The two hoses that have been removed from the CVT fluid warmer will be flushed first in one direction and then the other.

CAUTION: Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner. Spray Cooler Cleaner only in areas with adequate ventilation.  Avoid contact with eyes and skin. Do not breathe vapors or mist from spray.

1. Insert the “extension adapter hose”, from a can of Transmission Cooler Cleaner (Nissan P/N 999MP-AM006P), into one or the other of the disconnected CVT fluid cooler hoses
2. Flush CVT fluid cooler (radiator based) and hoses:
   1. Hold the hose and can as high as possible.
   2. Spray Transmission Cooler Cleaner, in a continuous stream, into the CVT fluid cooler inlet hose.
   3. Spray fluid until it flows out of the other hose for 5 seconds.
3. Slide a piece of 5/8 inch hose (16 mm) over the end of the CVT fluid cooler hose that was used as the flush inlet.
4. Insert the tip of an air gun into the end of 5/8 inch (16 mm) hose.
5. Blow compressed air, regulated to 5-9 kg/cm2 (70 – 130 PSI), through the CVT fluid cooler hose for 10 seconds to force out any remaining fluid.
6. Repeat steps 5 through 9 one additional time and then proceed to step 11.
7. Now reverse the direction that the hoses are being flushed and repeat steps 5 through 9 twice.  When completed proceed to step 12.
8. Reassemble the CVT fluid cooler hoses to the CVT warmer with new spring clamps in the reverse order of disassembly.

CVT Fluid Type and Fill Level

NOTE: The fluid change interval for the JF016E CVT is every 30,000 (heavy use)- 60,000 miles. Nissan NS-3 rated fluid should be used. The use of the incorrect fluid will lead to premature wear and overheating of the CVT and will invalidate the warranty coverage.

After the CVT has been installed in the vehicle, the CVT should be filled with fluid from the drain plug at the side of case by the bell housing. The volume of the CVT fluid is dependent on temperature, and when filling or adjusting CVT fluid level, the fluid temperature should be 35C – 45C (95 to 113°F).

CVT Fluid Fill Instructions

1. Engage the parking brake and lift up the vehicle.
2. Check that there is no CVT fluid leakage.
3. Remove the drain plug from the CVT oil pan.
4. After fluid has drained, reinstall drain plug.
5. Remove the overflow plug from the converter housing
   
6. Install the charging pipe set (KV311039S0) (A) into the overflow hole.
   
7. Tighten the charging pipe by hand.
8. Install the ATF changer hose to the charging pipe.  Press the ATF changer hose all the way onto the charging pipe until it stops.
9. Fill approximately 3 liters (3.2 US qt) of NS-3 CVT fluid.
10. Remove the ATF changing hose and changing pipe, then install the overflow plug.
11. Lift down the vehicle.
12. Start the engine.
13. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.  Hold the lever at each position for 5 seconds.
14. Check the scan tool to ensure the fluid temperature is 35°C (95°F) to 45°C (113°F).
15. Lift up the vehicle.
16. Remove the drain plug and then drain CVT fluid from the oil pan.
17. Repeat steps 6-16 one time
18. Tighten the drain plug to the specified torque
19. Remove the overflow plug
20. Install the changing pipe set into the overflow plug hold.  Tighten the changing pipe by hand.
21. Install ATF changer hose and charging pipe, then install the overflow plug.  Perform this quickly because the CVT fluid will leak.
22. Lift down the vehicle and start the engine.
23. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.  Hold the lever at each position for 5 seconds.
24. Check the scan tool to ensure the fluid temperature is 35°C (95°F) to 45°C (113°F).
25. Remove the overflow plug and confirm the CVT fluid is drained from the overflow plug hole.  Perform this while the vehicle is iding.  If the fluid does not drain, adjust the fluid level by adding ½ liter to the throught the overflow hole with the ATF filling tube, or through the oil filler pipe on the top of the transmission.
26. When the flow of the CVT fluid from the overflow plug hole slows to a drip, tighten the overflow plug.
27. Lift down the vehicle.
28. Using a scan tool, reset CVT Fluid Deterioration in the TCM
29. Stop the engine.

Alternative Fluid Level Check Procedure

The fluid level of the transmission can be checked though the oil filler pipe with a J-51155 tool or 23 ⅛ dipstick.

1. Park the vehicle on level ground (engine running, parking brake set).
2. Ensure that the CVT fluid operating temperature is within the range of 170°F-180°F (77°C-82°C).
3. Shift the transmission into REVERSE for 5 seconds.
4. Shift the transmission into DRIVE for 5 seconds.
5. Shift the transmission into REVERSE for 5 seconds.
6. Shift the transmission into PARK.
7. Remove the plastic cap from the filler tube and insert the J-51155 tool or 23 ⅛ dipstick
8. Reference the table below for proper fluid level

TCM Reprogramming – REQUIRED FOR WARRANTY

Programming is required for JF016E applications due to the high likelihood of judder codes and valve body codes if programming is skipped.  We will require proof of programming to honor any warranty involving valve body codes or judder codes.

Although the vehicle can be driven without programming, programming is required for the following reasons:

1. Solenoids are calibrated using the CD or calibration code on the range sensor
2. The TCM software is updated to the most recent version.
3. Programming rules out external (non-mechanical) causes of transmission failure.
4. Warranty coverage. See below for required documentation to demonstrate proof of programming.

Programming can be done with a Consult 3+ scanner and programmer (available at Nissan dealerships and with mobile programming services).  TCM programming requires a Consult 3+  At the time of writing (2025) the DrewTech RAP Kit is not able to do TCM programming on the JF016E and JF017E CVTs.

Proof of programming should include the VIN, odometer reading, date of programming, the previous TCM part number, and the TCM part number after programming

If you take the vehicle to a dealership for programming you will most likely be asked to provide a calibration CD with the programming file.  Berkeley Standard’s reman JF016E and JF017E CVT comes packaged with the CD. Alternatively, the dealership can identify and download the correct programming file using the QR code on the range switch (park-neutral safety switch).  If the QR code is missing from the range switch, send a message to contact@berkeleystandard.com with your VIN and a team member will reply to your message with the correct QR code for the vehicle.

NOTE: If there are any diagnostic trouble codes (DTC) the transmission may not program.  Clear all DTCs before proceeding with programming.  If there are persistent DTCs, these must be addressed and cleared before programming can proceed.
TEST DRIVE AND TRANSMISSION CALIBRATION

After the transmission has been installed use a scan tool to verify the vehicle does not have any diagnostic trouble codes.  If there are codes from the previous transmission, clear them with a scan tool and check if they return.  If the vehicle does not have any codes, test drive the vehicle for an additional 15 – 20 minutes to allow the TCM to self-calibrate.  Do not drive the vehicle if it has any DTCs that cannot be cleared before the test drive.

The test drive should cover a range of speeds in both forward and reverse. The vehicle may shift abnormally at the beginning of the test drive but should normalize in 20 minutes or less.  If the MIL / check engine light illuminates during the test drive, do not continue driving.  Re-scan the vehicle after the test drive to ensure there are no DTCs.

Make sure the engine coolant lines are not obstructed and coolant can freely flow into the CVT warmer/cooler. It is also important to inspect the engine air filter and replace it if dirty or obstructed. Excess engine temperature will overheat the CVT fluid and may cause premature failure.

The CVT fluid should also be inspected every 30,000 miles and replaced if burnt, contaminated, or otherwise degraded. Replace CVT fluid with NS-3 rated fluid only for all vehicles except the 2012 Versa, which used NS-2.

CVT Fluid Type and Fill Level

NOTE: The fluid change interval for the JF015E CVT is every 60,000 miles. If the vehicle has been driven over 60,000 miles on a Berkeley Standard CVT, maintenance records showing proof of fluid change(s) at 60,000 mile or earlier intervals must be provided in order to ensure warranty coverage.

NOTE: For Nissan Sentra and Versa model years 2013 and newer, Nissan NS-3 rated fluid should be used. For the 2012 Versa, NS-2 rated fluid should be used. Nissan NS-3 is NOT interchangable with NS-2. The use of the incorrect fluid will lead to premature wear and overheating of the CVT and will invalidate the warranty coverage.

After the CVT has been installed in the vehicle, the CVT should be filled with fluid from the drain plug at the bottom of the oil pan. There is an overflow tube in the oil pan that indicates the correct fluid level for this transmission. The volume of the CVT fluid is dependent on temperature, and when filling or adjusting CVT fluid level, the fluid temperature should be 35C – 45C (95 to 113°F).

CVT Fluid Fill Instructions

1. Engage the parking brake and lift up the vehicle.
2. Check that there is no CVT fluid leakage.
3. Remove the drain plug.
4. Install the charging pipe set (KV311039S0) (A) into the drain plug hole.
5. Tighten the charging pipe by hand.
6. Install the ATF changer hose to the charging pipe. Press the ATF changer hose all the way onto the charging pipe until it stops.
7. Fill approximately 3 liters (3.2 US qt) of NS-3 CVT fluid (NS-2 for 2012 Versa)
8. Lift down the vehicle.
9. Start the engine.
10. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position. Hold the lever at each position for 5 seconds.
11. Check the scan tool to ensure the fluid temperature is 35°C (95°F) to 45°C (113°F).
12. Lift up the vehicle.
13. Remove the drain plug and confirm that the CVT fluid is drained from the overflow tube. Perform this work with the vehicle idling.
14. If the CVT fluid does not drain reinstall the changing pipe and ½ liter of CVT fluid and repeat steps 8 – 12.
15. When the flow of CVT fluid slows to a drip, tighten the drain plug to the specified torque.
16. Lift down the vehicle.
17. Using a scan tool, reset CVT Fluid Deterioration in the TCM
18. Stop the engine.

Alternative Fill Procedure

1. Engage the parking brake and lift up the vehicle.
2. Check that there is no CVT fluid leakage.
3. Remove the drain plug and place a pan or container under the oil pan to catch excess fluid.
4. Remove the fill plug (see image below) near the CVT pass-through connector. The fill plug is near the bottom of the transmission and faces upwards.
5. Attach a hose or funnel to the open fill hole near the CVT pass-through connector.
6. Fill the transmission with NS-3 (NS-2 for 2012 Versa) CVT fluid until fluid comes out of the drain plug. The CVT will take approximately 3-4 liters (3.2-4.3 US qt) of NS-3 CVT (NS-2 for 2012 Versa) fluid before the fluid begins to drain.
7. Remove the hose or funnel and reinsert the fill plug. Lift down the vehicle.
8. Start the engine.
9. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position. Hold the lever at each position for 5 seconds.
10. Check the scan tool to ensure the fluid temperature is 35°C (95°F) to 45°C (113°F).
11. Lift up the vehicle.

TCM Reprogramming

The vehicle does not require programming unless the TCM software is affected by a service bulletin. To check the TCM software see instructions below:

First, find TCM Part Number with Scan Tool. The TCM hardware is a computer chip with identical hardware and the part number represents the software the TCM is programmed with. The TCM part number will start with 31036-XXXX.

If the TCM part number is any of the ones on the table below, the TCM needs to be reprogrammed with updated software. This can be done either with a Consult 3 scanner and programmer (available at Nissan dealerships), or with the RAP Kit but Drew Technologies.

NOTE: The JF015E transmission or valve body does not come with a programming CD.

NOTE: If there are any diagnostic trouble codes (DTC) the transmission may not program. Clear all DTCs before proceeding with programming. If there are persistent DTCs, these must be addressed and cleared before programming can proceed.

Test Drive and TCM Calibration

After the transmission has been installed use a scan tool to verify the vehicle does not have any diagnostic trouble codes. If the vehicle does not have any codes, proceed with the clutch point relearn (below), and test drive the vehicle for an additional 15 – 20 minutes to allow the TCM to self-calibrate. Do not drive the vehicle if it has any DTCs the cannot be cleared before the test drive.

The test drive should cover a range of speeds in both forward and reverse. The vehicle may shift abnormally at the beginning of the test drive but should normalize in 20 minutes or less. If the MIL / check engine light illuminates during the test drive, do not continue driving.

Re-scan the vehicle after the test drive to ensure there are no DTCs.

Clutch Point Relearn

The JF015E is a CVT combined with a two-speed transmission (auxiliary gearbox). When the valve body or transmission is replaced, the TCM must re-learn the shift point on the two speed transmission. The auxiliary gearbox is programmed to shift at 20 mph – 45 mph depending on engine RPM and load.

CAUTION: If clutch touch point learning is not performed, the auxiliary transmission may not shift or may shift at the wrong speed. You may feel shift shock when the auxiliary transmission shifts, especially between 20-45 mph and a downshift shock when decelerating below 10 mph.

NOTE: This manual procedure is only needed if the auto procedure is not available in C-III
Plus. If using an aftermarket scan tool, you must first erase TCM memory and TCM self learning data.

a. Start the engine and warm up the CVT fluid to 50°C (122°F).
NOTE: Confirm the CVT fluid temperature by “FLUID TEMP” in “Data Monitor”.
b. Turn the air conditioner OFF.
c. Move the shift selector to P, turn the ignition OFF, and then wait 5 seconds.
d. Start the engine and allow it to idle for 5 seconds.
e. Turn the ignition OFF and then wait 30 seconds.
f. Perform Step “e” to Step “f” two more times (Total: Three times).
g. Start the engine.
h. Allow engine to idle for 30 seconds.
i. Move the shift selector to D.
j. Accelerate the vehicle from 0 km/h (0 MPH) to 65 km/h (40 MPH) at low throttle
(0.5/8 – 1/8).
k. Decelerate the vehicle to 30 km/h (18 MPH) or less without using brakes.
l. Stop the vehicle and move the shift selector to P.
m. Turn the ignition OFF and wait 5 seconds or more.
n. Restart the engine.
o. Perform Step “j” to Step “o” four times (Total: Five times).
p. Move the shift selector to D.
q. Accelerate the vehicle from 0 km/h (0 MPH) to 45 km/h (28 MPH) at low throttle
(0.5/8 – 1/8).
r. Stop the vehicle and move the shift selector to P.
s. Turn the ignition OFF for 5 seconds or more and then restart the engine.
t. Perform Steps “q” to Step “t” four times (Total: Five times).
u. Drive the vehicle and check that no shock occurs while shifting gears.

Continuously Variable Transmission

Nissan started to explore the possibility of moving away from the usual automatic transmission in 2002 and became the first auto manufacturer in the world to use CVTs in cars. In the later years, CVTs became the default transmission in the Nissan models. This transmission offers simple and efficient power delivery offering great fuel economy than the traditional transmission systems.

CVTs became much popular as it offered step-less ratio changes between the different gears making gear shifting very smooth. You will not feel the shift shock while the transmission shift gears in drive mode. CVTs are so smooth that you many not even notice that the gears are being changed by the transmission.

Another reason for the popularity of CVT is that it is built using very few parts when compared to the traditional fixed gear automatic transmissions, making them cheaper to manufacture than the other five-speed transmissions. In addition, vehicles with CVTs offer higher fuel efficiency owing to less friction between parts and relatively low revving of the engine.

Taking Care of Nissan CVT

The basic differences between standard automatic transmissions and CVTs demand more care for CVT transmissions. Many people enquire about using non-Nissan aftermarket CVT fluids, but it is not advisable at all. CVT fluids from Nisan are designed as per the exact specifications of the Xtronic CVT and using third-party fluids will not serve the purpose.

One of the biggest problems with CVT relates to overheating. Many drivers regularly overfill their CVTs with transmission fluid assuming that more is good. However, you should fill the transmission fluid only up to the marks, which is about three quarters of the full reservoir. A simple thing you can do to prevent overheating of your Nissan Altima CVT engine is to check the freeze protection. This will help you confirm that all the settings of the vehicle are proper and that the CVT will not whine or go into failsafe mode.

As the automatic transmission of your car is an always-working part, there can be many early warning signs that you need to watch out for. Below are some of the important signs of CVT transmission problems.

Leakage

If you see pinkish oil leak marks when you move your car out of the parking area in the morning, it can be a classic sign of trouble. Transmission experts say that a CVT transmission can leak from about twenty external seals, some of which are very easy to repair and fix, whereas others will need complex services.

Vibration

Do you feel a bucking or shaking feel while commuting at high speeds? There can be two reasons for that, the first being a poor tuning and the second due to a malfunction in the transmission system of the vehicle. So if you feel shaking or vibrations while driving your car, take it to an experienced mechanic and get the vehicle transmission checked.

Delayed Drive

Another classic sign of a CVT transmission malfunction is a noticeable hesitation for the transmission of the car to engage a gear when you put the gear shifter in “D” or “R.” Issues like low transmission fluid, a loose belt, or a failing clutch pack of an internal transmission seal can cause the delay in gear engagement.

Burning Smell

If you sense a burning smell when you are near your car, it can be a sign of an overheating transmission. The burning smell can also be caused due to the transmission fluid leaking into the exhaust system. If the burning smell is caused by the leak of transmission fluid to exhaust system, it should be addressed immediately.

Transmission Slips

Transmission slip is a situation where the engine is revving fast but the complete power is not transferred to the wheels. There can be a number of reasons for transmission slips and it would be better to take your ride to a technician for a checkup before things get worse.

Most manufacturers replace the items that are entirely worn out in the case of a rebuilt transmission, which means that the items that are marginally good will not be replaced. A rebuilt and repaired transmission might work well sometimes, but it will not be as good as a remanufactured transmission. On the other hand, all the worn items in the automatic transmission will be replaced in case of a remanufactured transmission. Even the marginally good parts that are still working will be completely replaced or re-machined. This makes remanufactured transmission a much better choice when compared to opting for a rebuilt transmission.

Remanufactured transmissions are also a lot more different from the transmissions that are simply rebuilt or repaired by including a few updates, which the factory should have initially included in the main design of the transmission in the first place. Remanufactured transmissions usually include slight modifications to the valve body and the machining of the internal parts of the transmission to extend its life and performance.

Additionally, some remanufacturers also prefer to use better quality friction materials to the transmission during the remanufacturing process to make it more efficient. These kind of modifications, which are implemented by the remanufacturers to boost the durability and lifespan of the transmission, are absent in most rebuilt transmissions.

Several rebuild shops in the country do not even have the right equipment for handling the repairs on an automatic transmission, which has undergone a severe failure. These rebuilding shops also have no access to high-pressure hot tanks, which are specially designed to thoroughly clean the small passages of the automatic transmission. At Berkeley Standard, we have the most up to date technology and tools, which allow us to produce high-quality remanufactured transmissions with ease. Get in touch with us today to see how we can help.
