Fitment: 2011- Early 2015 GM 6.6L Duramax. The A40 and A50 TCM that is used to control the Allison 6-speed automatic transmission is the weak link of the Allison transmission.\u003c\/p\u003e\u003cp\u003eThis is due to delicate thin wires inside the TCM that contact one another overtime and short-out the entire module. In 2022, Allison sent out a letter (SIL 15-1K2K-22) announcing the discontinuation of support for the A50 and A40.\u003c\/p\u003e\u003cp\u003eThis effectively left over 10,000 Duramax owners out of their trucks. So we got to work developing a solution utilizing our Translator technology found in the ATS Allison Conversion to help get these trucks back on the road, shifting and holding power even better than before, ASAP!\u003c\/p\u003e\u003cp\u003eThe A50 and A40 TCM have been used in all GM Duramax\/Allison Diesel Trucks produced from 2006 to 2017.
