This BD's Torqloc transmission controller is a must - have for your automatic transmission. It fits various vehicle models from 1990 - 2005, including Ford F - Series with 7.3L Powerstroke, Dodge Ram with 5.9L Cummins, and GMC/Chevrolet with 6.5L Duramax. It effectively prevents high temperatures caused by torque converter slippage. While most torque converters transfer only 10% to 80% of the retarding force through the fluid coupling, BD's autoloc transfers 100%. When the Exhaust Brake is activated, it commands the lock - up clutch of the torque converter to stay engaged. Part Number: 1030395. Key features include maintaining lock - up during exhaust brake activation, ensuring 100% retarding force transfer in 3rd and 4th gears, preventing slippage and high oil temperatures. The TorqLoc has a three - position switch for manual lock - up command, AutoLoc, and stock operations.

Using this Torqloc transmission controller is easy. First, make sure it is installed correctly according to your vehicle's model and engine type. When you activate the exhaust brake, the controller will automatically command the lock - up clutch of the torque converter to stay engaged. You can also use the three - position switch on the TorqLoc for manual lock - up control. As for maintenance, regularly check the connections to ensure they are secure. If you notice any abnormal performance, like unusual noises or temperature changes, it's a good idea to have it inspected by a professional. Always follow your vehicle's maintenance schedule as well to keep the whole system in top condition.
