Transmission Cooler: Component Tests and General Diagnostics
NOTE: The transmission linkage/cable 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 transmission case.
5. Connect one end of a hose to the cooler return line and route the other end of the hose 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 transmission in neutral range.
8. When fluid flowing from hose is all liquid, an adequate amount of fluid should be observed (approximately 1 liter [1 quart] delivered in 30
seconds). If adequate flow is observed, test is completed.
9. If the flow is not adequate, stop engine. Disconnect hose from cooler return line and connect it to converter out line fitting (front fitting) on
transmission case.
10. Repeat Steps 7 and 8. If flow is now adequate, refer to the Symptom Chart.
If flow is not adequate, service pump and/or converter assembly, and main control.
