NOTE: The Transmission Control Switch (TCS) is not a serviceable component. Repairs to the TCS must not be attempted. The TCS must be replaced as an assembly.

The Transmission Control Switch (TCS) is a rotary switch installed in the floor console. The TCS controls the driver transmission selections.

By selecting PARK, REVERSE, NEUTRAL, DRIVE or SPORT on the TCS, the transmission functions as any conventional automatic unit. The TCS is a magnetic system using position sensors to determine the position of the selector. The TCS is a fully electronic rotary transmission selector with no mechanical connection to the transmission.

The TCS rises from the floor console once the engine is running. When the engine stops, the TCS automatically resets to the PARK position and the transmission engages into PARK. The only exception is if the TCS is moved to the NEUTRAL position when the engine is stopped. When the engine is stopped with the TCS in any position other than NEUTRAL, the TCS retracts into the floor console.

If the TCS is in the NEUTRAL position when the engine is stopped, the TCS remains in the raised position for 10 minutes. This is to enable the vehicle to be stopped in a drive through car wash for example. After 10 minutes the TCS automatically retracts, the TCS automatically resets to the PARK position and the transmission engages into PARK. The TCS also retracts if PARK is selected within the 10 minutes period.

NOTE: When PARK is selected the Electric Park Brake (EPB) is automatically applied. The EPB is also automatically applied when the engine is stopped. The EPB automatic application can be overridden by holding the EPB switch in the release position and within 5 seconds stop the engine. Hold the EPB switch for a further 2 seconds after the engine has stopped. This allows the vehicle to be in the NEUTRAL position with the EPB not applied.

Under a low startup battery voltage condition, the TCS may be slow to rise or may fail to rise from its docked position. Once the engine is running, the retracted TCS can still be rotated to select gear positions other than PARK. The operation can only be done in exceptional or emergency situations.

CAUTION: If the Transmission Control Switch (TCS) fails to rise, the TCS must only be rotated under exceptional circumstances. Once rotated the TCS may become mechanically locked and following an engine stop require replacement.

The Transmission Control Switch (TCS) contains an internal interlock solenoid to prevent the TCS from being rotated when the engine is not running.

The Light Emitting Diodes (LED) in the TCS is illuminated to display the selected position. If the selected position is not performed by the transmission, the selected position LED flashes.
