Transmission Fluid Cooler Flow Test

Note: The transaxle linkage/cable adjustment, fluid level and line pressure must be within specification before carrying out this test.

1. Remove fluid level indicator from fluid filler tube.
2. Place funnel in fluid filler tube.
3. Raise the vehicle on a hoist and place suitable safety stands under the vehicle.
4. Remove the cooler return line (lower fitting) from the fitting on the transmission case.
5. Connect one end of a hose to the cooler return line and route other end of the hose up to a point where it can be inserted into the funnel at the fluid filler tube.
6. Remove the safety stands and lower the vehicle. Insert end of hose into the funnel.
7. Start the engine and run it at idle with the transaxle in NEUTRAL position.
8. When the fluid flowing from the hose is in a steady stream, a liberal amount of fluid should be observed. "Liberal" is described as about 1 liter (1 quart) delivered in 30 seconds. If a liberal flow is observed, the test is complete.
9. If the flow is not liberal, stop the engine. Disconnect the hose from the cooler return line and connect it to the converter outline fitting (upper fitting) on the transaxle case.
10. Repeat Steps 7 and 8. If flow is now approximately 1 liter (1 quart) in 30 seconds refer to the transaxle removal procedure for cleaning and backflushing. If the flow is still not approximately1 liter (1 quart) in 30 seconds, repair the pump or the torque converter.
