Description and Operation
Introduction
Driver gearshift control is effected by:
The gear shift lever. The accelerator pedal position. The kickdown switch (where fitted). The performance mode pushbutton.
Driver's Selector Module ('J' Gate)

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 transm ission control module via the rotary switch.
ItemPart NumberDescription
1—Gear selector lever
2—Drive-to-fourth switch connector
3—Neutral position switch connector
4—Park position switch connector
5—Gear selector illumination module
6—Gear selector interlock solenoid
7—Security system Active LED

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 leve r is moved to the Park position.
The gear selector module:
Provides illumination of the gear sele ctor surround, which is dimmable via a CA N 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 se lector surround, in response to an input from the body
processor module.
Is connected to the fascia harness via a 12-way connector. Refer to Connec tor Pins Identification, 307-01A.
The gear selector interlock solenoid:
Prevents the gear selector lever from be ing moved from the Park position, unless th e 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 wh eels (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.
Performance Mode Pushbutton

The performance mode pushbutton:
Is mounted on the gear selector surround. Selects Normal or Sport mode when pressed by the driver. Is illuminated when Sport mode is selected.
