- Disconnect both hoses from the oil cooler pipes. Connect the oil cooler feed pipe (bottom connector) to the transaxle and the return pipe (top connector) to the discharge hose (5). This may require (J 35944-600). Clip the discharge hose (5) onto the empty oil drain container. See Figure.
- Confirm the transaxle is filled with ATF. See CHECKING FLUID LEVELS . Start the engine with the transaxle in PARK and run for 30 seconds. A minimum of 2 qts. (1.9L) must be discharged during this 30-second run time. If fluid flow is greater than 2 qts. (1.9L) in 30 seconds, go to next step. If fluid flow is less than 2 qts. (1.9L) in 30 seconds, go to step 4.
- Remove the discharge hose (5), reconnect the cooler feed and return pipes to the transaxle and refill the unit to the proper fluid level. Inspect the transaxle oil cooler pipe connections at the radiator, the auxiliary cooler (if equipped) and the transaxle for leaks.
- 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. See Figure. Start the engine with the transaxle in PARK range and run for 30 seconds. A minimum of 2 qts. (1.9L) must be discharged during this 30-second run time. Perform the following according to the flow rate:
- Insufficient feed flow: Inspect the transaxle.
