WELCOME
Thank you for purchasing the BD TorqLoc Kit. This manual is to aid you with your
installation and operation of the unit. We strongly suggest that you retain this
manual for any future reference.
NOTE: For trucks with a Jacobs Exhaust Brake system for the Dodge ISB 24
valve application, and all US Gear D-Celerators, this brake cannot be hooked
up to the module. Follow the instructions that are for "Without Exhaust
Brake" on page 10.
The BD TORQLOC Advantage
Exhaust brake usage can cause high temperatures in the automatic transmission
due to torque convertor 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
convertors.
The BD TorqLoc commands the lock-up clutch of the torque convertor to stay
engaged when the BD Exhaust Brake is activated. This allows up to 100% of the
retarding force to be transferred while in 3rd and 4th gear. Also, transmission oil
temperatures will remain low because of little or no slippage occurring in the
convertor in these gears.
