TorqLoc Transmission Controls

Torque convertors in the newer trucks have 2 stages. A fluid coupling occurs first when you are starting, accelerating or pulling up a big hill. When you are cruising at a constant speed the lock up portion of the converter is engaged and 100% of each rpm is transferred through the converter, just like a standard clutch.

The first position of the TorqLoc switch manually locks up the convertor clutch just like a standard transmission. This results in lower transmission temperature and excellent transfer of retarding hp when slowing down. The second position returns the truck to a stock application. The third position reverts to AutoLoc function and is good to drive in this mode 100% of the time.

The computer will automatically disengage the lock up clutch at 25 mph to prevent the engine from stalling if you forget to switch the lock up off.
