Transmission Fluid Cooler Flow Test

NOTE: The transaxle linkage adjustment, fluid level and line pressure must be within specification before performing this test.

1. Remove fluid level indicator from fluid filler tube.
2. Place funnel in fluid filler tube.
3. Raise vehicle on hoist and position suitable safety stands under vehicle.
4. Remove cooler return line (rear fitting) from fitting on transaxle case.
5. Connect one end of a hose to the cooler return line and route the other end of the hose up to a point where it can be inserted into the funnel at the fluid filler tube.
6. Remove safety stands and lower vehicle. Insert end of hose into funnel.
7. Start engine and run at idle with transaxle in NEUTRAL range.
8. When fluid flowing from hose is all liquid, an adequate amount of fluid should be observed. Approximately 1/2 liter (1/2 quart) of liquid delivered in 30 seconds. If adequate flow is observed, test is completed.
9. If flow is not adequate, stop engine. Disconnect hose from cooler return line and connect it to converter-out line (front fitting) on case.
10. Repeat Steps 7 and 8. If flow is now liberal, perform back flushing and cleaning procedures in Cleaning and Inspection. If flow is still not liberal, repair the pump and/or converter.
