BD Diesel 1031312 Auto Transmission Control Module

The Allison transmission control strategy works very well, even allowing torque converter clutch lockup in second gear in some cases. However, in high horsepower applications lockup is sometimes inhibited due to increased torque converter stall speed. Because of this, auxiliary lockup control devices are required to reliably engage the clutch for racing or high performance applications. The BD Allison Lockup Controller gives you control over your torque converter clutch. The module is equipped with different automatic modes that will automatically engage the TCC when the truck is at high boost based on current gear or a set mile-per-hour. Additionally the module can be setup to use an override switch that will allow TCC operation at any speed as long as it won't stall the engine. TCC apply is firmer than stock but is cushioned by using PWM ramp up to prevent excessively harsh engagement.Allison transmissions (LML) utilize variable line pressure that adjusts to different engine load to reduce heat buildup in the transmission and improve fuel economy. The problem with this is that it drops line pressure after a shift, causing clutch slippage and failure in higher powered trucks. The BD module is equipped with a pressure controller that boosts line pressure up to 275psi when the engine is over 15psi boost and runs stock pressure under normal conditions to prevent harsh shifting.

Description_MKT	The Allison Lock-Up and Pressure Controller for Chevy Duramax pick-ups delivers up to 275psi line pressure inside the transmission, giving 25% to 115% more theoretical holding power and help prevent burned up clutches - a great way to increase the longevity of the Allison transmission for towing, street and race applications. Unlike simple solenoid foolers or plugs which are active all the time, the Allison Pressure Controller is only operational when turbo boost exceeds 15psi, and, does not create extra heat when inactive or cause clunky/unusual shifts. Comes with three automatic torque converter lockup modes that are engage based upon turbo boost and enables torque convertor lockup in 2nd gear, 3rd gear or, based on vehicle speed. Includes manual lockup switch which the controller protects the engine from stalling if still engaged at too low of speed. Installs quickly in under an hour.
