BDD TorqLoc

Currently, exhaust brake usage can cause high temperatures in the automatic transmission due to torque converter slippage, and, only 10% to 80% of the retarding force is transferred through the fluid coupling of most torque converters. The BD Torq/UnLoc commands the lock-up clutch of the torque converter to stay engaged when the BD Exhaust Brake is activated. This allows for up to 100% of the retarding force to be transferred in 3rd and 4th gear and the transmission oil temperature to remain low because of little to no slippage occurring when the converter is in these selected gears. The BD Torq/UnLoc is also able to prevent the ECM from activating the lock-up clutch when such an action would drag the engine rpm out of the optimum torque range, or, when traveling at such speeds that would cause the ECM to cycle the lock-up clutch in and out. Command the torque converter to stay locked, stay unlocked, or revert to OEM settings with the BD TorqLoc. Flip the toggle switch to position one, and the lock-up clutch is engaged, so transmission temperature remains low and the exhaust brake can work with 100-percent effectiveness (this is a manual setting and should only be selected under light load/light power conditions, such as highway driving). Position two reverts back to stock function, or can be wired to unlock the torque converter. Position three acts as an AutoLoc by commanding lock-up only when the exhaust brake is engaged - perfect setting for every day driving in all situations. Additionally, the TorqLoc has an Overdrive inverter option which allows the transmission to start out in Drive which will prevent upshift into the Overdrive gear - great for those who live in city/urban areas. Also, if you have a BD Valve Body with the second gear lock-up capability, the lock-up can be set to hold until 5-10 mph. Also available is the Torq/UnLoc which acts the same as the TorqLoc but in the third position the converter is prevented from locking up.
