Transmission Controllers

Control your torque convertor lockup and pressure settings with BD's new Allison controller kit your 2011-2015.5 GMC/Chevy Duramax 6.6L with the LML engine.

The BD AutoLoc commands the torque converter to lock up, and stay locked up, any time the exhaust brake is applied in third and fourth gears. This not only helps with engine braking, but because there’s no clutch slippage, transmission oil temperatures remain low.

The A50 and T14 TCM that is used to control the Allison 6-speed automatic transmission is the weak link of the Allison transmission. This 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 T14 TCMs. This effectively left over 10,000 Duramax owners out of their trucks.
