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.
