This setting offers “A” and “B” modes. You can set up two different COMPUSHIFT configurations in advance, and use the mode switch to change between them.
TCC Mode A Automatic
TCC mode refers to the torque converter clutch. In previous models of COMPUSHIFT, the TCC was always automatically active, meaning it is preset at the specified MPH and selected gear.
COMPUSHIFT II introduces a new mode called “manual mode”, in which the TCC is controlled by a switch, either on or off, based on driver input.
The default setting is Automatic, and you can change it to Manual if needed.
Manual TCC mode is only applicable for special vehicle setups, not as a standard.
