Transmission/Transaxle Cooling - 4.0L NA V8 - AJ27/3.2L NA V8 - AJ26 -
Transmission Cooling
Description and Operation
The transmission fluid cooling system maintains fluid temperature within specified limits.

Parts List
Component Descriptions
The transmission fluid pipes:
Transfer fluid from the transmission to the cooler under the action of the hydraulic system pump. Return the cooled fluid from th e cooler to the transmission.
The transmission fluid cooler:
Is a plate type made from aluminum. Is mounted in the engi ne cooling radiator right-hand end tank.
Overheating Protection
If the engine coolant or transm ission fluid temperatures exceed their predefined limits, th e transmission control module locks
the torque converter clutch. By reducing slip, this minimises th e amount of heat transferred to the engine cooling system from
the transmission fluid.

ItemPart NumberDescription
1—Fluid pipe, oil FROM cooler
2—Fluid pipe, oil TO cooler

Transmission/Transaxle Cooling - 4.0L SC V8 - AJ26 - Transmission
Cooling
Description and Operation
The transmission fluid cooling system maintains the fluid temperature within specified limits. The cooling element is located
in the engine cooling radiator LH end tank.
Fluid is circulated, under pressure, by the transmission pump to the cooler.
General Layout

Overheating Protection
If the engine coolant or transmission fluid temperatures exceed their predefined limits, the transmission control module
locks the torque converter clutch . By reducing slip, this minimises the amount of heat transferred to the engine cooling
system from the transmission fluid.

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.
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.
