Normal Operation and Fault Conditions
The TCS is a momentary contact switch located on the selector lever. Pressing the TCS will engage or disengage the O/D function of the transmission. When the O/D is disengaged, the O/D icon illuminates OFF on the IPC. Each time the ignition switch is cycled, the transmission automatically provides O/D operation regardless of TCS position the last time the engine was running.
