Automatic Transmission/Transaxle External Controls - 4.0L NA V8 -
AJ27/3.2L NA V8 - AJ26 - External Controls
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.
