Transmission Selector Lever
The transmission selector lever:
^ Has seven positions: PARK, REVERSE, NEUTRAL, DRIVE, FOURTH, THIRD and SECOND.
^ Operates the transmission selector shaft in the PARK, REVERSE, NEUTRAL and DRIVE positions by means of a cable.
^ Passes driver gearshift requests to the engine control module (ECM) via the rotary switch.
^ Uses Hall effect switches and a micro controller inside the transmission selector lever to generate the electronic code.
^ When moved to the left-hand side of the transmission selector lever allows manual electronic selection of FOURTH, THIRD and SECOND gears.

The NEUTRAL position switch:
^ Is incorporated within the transmission rotary switch.

The transmission selector illumination module:
^ Provides a red transmission lever position illumination to indicate the selected gear.
^ Provides a green background for the transmission selector lever.

The transmission selector interlock solenoid:
^ Prevents the transmission selector lever from being moved from the PARK position, unless the ignition switch is in ON position, and the brake pedal is pressed.
^ Is controlled by an input from the ECM via the CAN bus.

The seven transmission selector positions are:
^ P: The transmission is mechanically locked (starting enabled).
^ R: Reverse gear.
^ N: No power to the road wheels (starting enabled).
^ D: All 5 forward gears available.
^ 4: Upshift to 4th gear only.
^ 3: Upshift to 3rd gear only.
^ 2: Upshift to 2nd gear only.

The performance mode push button:
^ is mounted on the transmission selector surround.
^ selects Normal or Sport mode when pressed by the driver.
^ is illuminated when Sport mode is selected.
^ is hard-wired to the ECM.

The transmission selector at the transmission unit:
^ is connected to the driver's selector module by a cable.
^ operates the manual selector valve, which is part of the electro-hydraulic control unit.
^ operates the rotary switch, which is connected to the ECM.

The transmission selector cable provides the positive link between the selector lever and the transmission. The transmission selector cable does not require adjustment.
