The gear selector lever:

• Has seven positions: Park, Reverse, Neutral, Drive, Fourth, Third and Second.
• Operates the transmission selector shaft and rotary switch, in all positions (except Drive-to-fourth) by means of a Bowden cable.
• Passes driver gearshift requests to the transmission control module via the rotary switch.

The Drive-to-fourth switch:

• Detects when the gear selector lever is moved from Drive to Fourth.
• Is hard-wired to the transmission control module.

The Neutral position switch:

• Is hard-wired to the body processor module.
• Detects when the gear selector lever is moved to the Neutral position.

The Park position switch:

• Is hard-wired to the body processor module.
• Detects when the gear selector lever is moved to the Park position.

The gear selector module:

• Provides illumination of the gear selector surround, which is dimmable via a CAN signal from the instrument cluster.
• Provides red illumination, on the gear selector surround, of the gear selected, by CAN signals from the instrument cluster.
• Illuminates the security system Active LED on the gear selector surround, in response to an input from the body processor module.
• Is connected to the fascia harness via a 12-way connector.

The gear selector interlock solenoid:

• Prevents the gear selector lever from being moved from the Park position, unless the ignition switch is in position II, and the brake pedal is depressed.
• Is controlled by an input from the body processor module.

The seven gear selector positions are:

• P : The transmission is mechanically locked (starting available).
• R : Reverse gear.
• N : No power to the rear wheels (starting available).
• D : All 5 forward gears available.
• 4 : Upshift to 4th gear only.
• 3 : Upshift to 3rd gear only.
• 2 : Upshift to 2nd gear only.
