Transmission Mode Switch: Description and Operation
Power/Economy Mode Switch, A/T
Transmission Control Switch (TCS)
DESCRIPTION
The Transmission Control Switch (TCS) is a momentary contact switch which disables 4th gear operation and enables engine braking when
activated.
OPERATION
When the switch is pressed, a signal is sent to the Powertrain Control Module (PCM). The PCM then energizes the Transmission Control
Indicator Lamp (TCIL) and the Coast Clutch Solenoid (CCS), applying the coast clutch to provide engine braking and cancels fourth gear
operation.
