GM 6T40 Transmission
Berkeley Standard completely disassembles each GM 6T40 we remanufacture. Every component is cleaned, tested, and repaired or replaced if not to 100% OE specifications. We replace all seals, gaskets, clutches, bushings, and filters. Our remanufacturing facility is state-of-the art and our processes are ISO 9001/TS 16949 certified. Each remanufactured transmission is tested on over 200 parameters on both the component-level and as a complete unit on our testing unit that simulates live operations on a vehicle. We offer a limited 2-year unlimited mileage warranty.
