Flow Check

Important:
Refer to Table 1 to determine the correct pipe for each application.





1. Disconnect both hoses from the oil cooler pipes. Connect the oil cooler feed pipe to the transmission and the return pipe to the discharge hose (5). Clip the discharge hose (5) onto the empty oil drain container.

2. Confirm the transmission is filled with automatic transmission fluid. Refer to SPECIFICATIONS in Section 7 of the appropriate Service Manual for the correct automatic transmission fluid capacity.

3. Start the engine with the transmission in PARK range and run for 30 seconds. A minimum of two (2) quarts (1.9 L) must be discharged during this 30 second run time.

^ If fluid flow is greater than 2 qt (1.9 L) in 30 seconds, go to step 4.

^ If fluid flow is less than 2 qt (1.9 L) in 30 seconds, perform the following diagnosis:

Disconnect the oil cooler feed line at the radiator. Connect the discharge hose (5) to the cooler feed line. Clip the discharge hose (5) to the empty oil drain container. Start the engine with the transmission in PARK range and run for 30 seconds. A minimum of two (2) quarts (1.9 L) must be discharged during this 30 second run time. Do the following according to the flow rate:

- Insufficient feed flow: inspect the transmission

- Sufficient feed flow: inspect the oil cooler return pipe and the oil cooler (and auxiliary cooler, if equipped).

4. Remove the discharge hose (5), reconnect the cooler feed and return pipes to the transmission and refill the unit to the proper fluid level. Inspect the transmission oil cooler pipe connections at the radiator, the auxiliary cooler (if equipped) and the transmission for leaks. Refer to Section 7 of the appropriate Service Manual.
