Transmission Cooler: Testing and Inspection
TRANSAXLE FLUID COOLER
Transaxle Cooling
When internal wear or damage has occurred in the transaxle, metal particles, clutch plate material or band material may have been carried into the torque
converter and transaxle fluid cooler. These contaminants are a major cause of recurring transaxle concerns and must be removed from the system before
the transaxle is returned for repair.
Transaxle Fluid Cooler Flow Test
NOTE:The selector lever linkage, selector lever cable adjustment, transaxle fluid level and line pressure must be within specification before carrying out
this test. See See: Shift Linkage/Shift Cable/Adjustments/Selector Lever Cable Adjustment for selector lever linkage and selector lever cable adjustment
and see See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Special Testing Procedures for line pressure test. The transmission fluid
must be above 82°C (180°F) for the cooler by-pass to open to carry out this test.
1. Using a scan tool, run the engine to establish the correct transaxle fluid temperature of 82°C (180°F).
2. Remove the transmission fluid level indicator from the transaxle fluid filler tube.
3. Place a funnel in the transaxle fluid filler tube.
4. With the vehicle in NEUTRAL, position it on a hoist. See See: Maintenance/Vehicle Lifting/Service and Repair/Lifting.
5. Remove the transaxle fluid cooler return tube (rear fitting) from the fitting on the transaxle case.
6. Connect one end of a hose to the cooler return tube and route other end of the hose up to a point where it can be inserted into the funnel at the
transaxle fluid filler tube.
7. Start the engine and run it at idle with the transaxle in NEUTRAL position.
