Transmission Fluid Cooler Flow Check

NOTE: The transmission linkage/cable adjustment, fluid level and line pressure must be within specification before performing this test. Refer to service procedures as outlined.

1. Remove oil level indicator (7A020) from oil filler tube (7A228).

2. Place funnel in oil filler tube.

3. Raise vehicle on a hoist and place suitable safety stands under vehicle.

4. Remove cooler return line (rear fitting) from fitting on transmission case (7005).

5. Connect one end of a hose to cooler return line and route other end of hose up to a point where it can be inserted into funnel at oil 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 position.

8. When fluid flowing from hose is solid, a liberal amount of fluid should be observed. "Liberal" is described as about 0.5 liter (16 oz) delivered in 30 seconds. If liberal flow is observed, test is completed.

9. If flow is not liberal, 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 liberal, refer to the Cleaning and Inspection —Converter and Oil Cooler and Transmission Cooler and Lines, Backflushing and Cleaning. If flow is not liberal, service pump and/or torque converter (7902) assembly.
