BD Diesel Performance TorqLoc Converter Control
First Position should only be used manually (just like gears would be selected). Converter clutch and drive clutch designs have torque limitations so only use this function under light load and/or light power conditions.
Second Position reverts to stock, or wire it to unlock converter.
Third Position can be selected for daily use, retarding, or driving under heavy load and/or power.
TorqLoc also has an overdrive inverter option for the transmission to start in drive. The lock-up can be set to hold on until 5-10 mph if you have second gear lock-up for slow driving conditions.
