The Allison transmission is known for its reliability and strength, other than one weak link, the factory A40/A50 TCM. The delicate thin wires inside the TCM that contact one another can short out the entire module. In 2022, Allison realized this issue and sent out a letter (SIL 15-1K2K-22) announcing the discontinuation of support for the A50 and A40. This effectively left over 10,000 Duramax owners out of their trucks. When this happened, ATS got to work. Utilizing ATS's Translator technology that is used in the Allison conversion kits, ATS developed a solution that gets your Duramax back on the road with better shifting and better holding power like you have never felt before.
Found on the current 2023 Duramax, the T87a TCM has a much faster processor than the A50 and that equates to better shift quality, faster shifting and overall improved drivability. This is a direct replacement upgrade that requires no permanent modifications and features a plug and play OEM quality harness and module. Designed for stock or modified trucks, this T87 TCM comes in an assembly including ATS's Translator module that also has their Co-Pilot transmission functions built in.
