Sensors
Speed Sensors
The turbine speed sensor and the output shaft speed sensor are Hall effect type sensors located in the Mechatronic valve block
and are not serviceable items. The TCM monitors the signals from each sensor to determine the input (turbine) speed and the output shaft speed.
The turbine speed is monitored by the TCM to calculate the slip of the torque converter clutch and internal clutch slip. This signal allows the TCM to accurately control the slip timing during shifts and adjust clutch application or release pressure for overlap shift control.
The output shaft speed is monitored by the TCM and compared to engine speed signals received on the CAN bus from the ECM. Using a comparison of the two signals the TCM calculates the transmission slip ratio for plausibility and maintains adaptive pressure control.
Temperature Sensor
The temperature sensor is also located in the Mechatronic valve block. The TCM uses the temperature sensor signals to determine the temperature of the transmission fluid. These signals are used by the TCM to control the transmission operation to promote faster warm-up in cold conditions or to assist with fluid cooling by controlling the transmission operation when high
fluid temperatures are experienced. If the sensor fails, the TCM will use a default value and a fault code will be stored in the TCM.
Damper
There is one damper located in the valve housing. The damper is used to regulate and dampen the regulated pressure supplied
via EPRS. The damper is load dependent through modulation of the damper against return spring pressure.
The damper comprises a piston, a housing bore and a spring. The piston is subject to the pressure applied by the spring. The
bore has a connecting port to the function to which it applies. Fluid pressure applied to the applicable component (i.e. a
clutch) is also subjected to the full area of the piston, which moves against the opposing force applied by the spring. The
movement of the piston creates an action similar to a shock absorber, momentarily delaying the build up of pressure in the
circuit. This results in a more gradual application of clutches improving shift quality.
Spool Valves
The valve block spool valves control various functions of the transmission. The spool valves are of conventional design and are
operated by fluid pressure.
Each spool valve is located in its spool bore and held in a default (unpressurized) position by a spring. The spool bore has a
number of ports which allow fluid to flow to other valves and clutches to enable transmission operation. Each spool has a
piston which is waisted to allow fluid to be diverted into the applicable ports when the valve is operated.
When fluid pressure moves a spool, one or more ports in the spool bore are covered or uncovered. Fluid is prevented from
flowing or is allowed to flow around the applicable waisted area of the spool and into another uncovered port. The fluid is
either passed through galleries to actuate another spool, operate a clutch or is returned to the fluid pan.

30. CAUTION: Observe the engine temperature warning light. If the
warning light is displayed, switch off immediately and allow to cool.
Failure to follow this instruction may cause damage to the vehicle.
Raise the engine speed to 2000 RPM and maintain at 2000 RPM until the
engine cooling fan operates.
31. CAUTION: Switch off the engine and allow the coolant temperature
to go cold.
Switch the engine off and allow to cool.
32. Visually check the engine and cooling system for signs of coolant
leakage.
33. WARNINGS:
When releasing the cooling system pressure, cover the coolant
expansion tank cap with a thick cloth.
Since injury such as scalding could be caused by escaping steam or
coolant, make sure the vehicle cooling system is cool prior to carrying
out this procedure.
CAUTIONS:
Make sure the coolant level remains above the "COLD FILL RANGE"
lower level mark.
Anti-freeze concentration must be maintained at 50%.
NOTE: When the cooling system is warm, the coolant will be
approximately 10mm above the upper level mark on the expansion tank
with the cap removed.
Check and top-up the coolant if required.

Transmission/Transaxle Cooling - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol - Transmission Cooling - Overview
Description and Operation
OVERVIEW
Transmission cooling is provided by a transmission fluid cooler, which transfers heat from the transmission to the engine
cooling system. The transmission fluid cooler is attached to a mounting bracket on the front subframe, in the front left corner
of the engine compartment.
Two hose and pipe assemblies connect the transmission fluid cooler to the automatic transmission. Two engine coolant hose
connections are incorporated into the top of the transmission fluid cooler for the supply and return of coolant from the engine
cooling system. For additional information, refer to 303-03D Engine Cooling.
