Dodge Ram 3500 Transmission Controllers

If your torque converter is not locked up when the exhaust brake is applied, you are only benefiting from a fraction of its retarding power. 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 hel...

ProTect68 Trans Pressure Control kit delivers 150% of the torque holding force to stock transmissions like no others can. Industry leading custom bonded gasket valve body separator plate and gaskets substantially reduces cross leaks compared to stock and other aftermarket kits, even with much higher...

Industry leading custom bonded gasket valve body separator plate substantially reduces cross leaks compared to stock and other aftermarket kits, even with much higher line pressures - up to 250psi. Kit includes a heavy duty accumulator plate to prevent accumulator blow-out. Ideal for use with EFI Li...

Exhaust brake usage can cause high temperatures in the automatic transmission due to torque converter slippage if a lockup device is not used. Only 10% to 80% of the retarding force is transferred through the fluid coupling of most torque converters. The BD TorqLoc commands the lock-up clutch of the...

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 conv...

Vehicle maneuverability is reduced while in 4WD. When the 2Low Unloc is turned on, you disable the front wheel drive mechanism allowing for full torque to be available to the rear wheels only. The front wheels will NOT be driven, delivering normal 2WD maneuverability while in low range! This will al...
