Flow Check
WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect both hoses from the oil cooler pipes. Connect the oil cooler feed pipe, vertical/top connector, to the transmission and the return pipe, horizontal/bottom connector to the discharge hose (5). Clip the discharge hose (5) onto the empty oil drain container. See Fig 1 .
- Confirm the transmission is filled with automatic transmission fluid. See FLUID CAPACITIES .
- Start the engine with the transmission in PARK range and run for 30 seconds. A minimum of 2 quarts (1.9L) must be discharged during this 30 second run time. If fluid flow is greater than 2 quarts (1.9 L) in 30 seconds, proceed to 5 . If fluid flow is less than specified, go to next step.
- If fluid flow is less than 2 quarts (1.9L) 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 2 quarts (1.9L) 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.
- Remove the discharge hose (5), reconnect the cooler feed and return pipes to the transmission and refill the unit to the proper fluid level. See FLUID CAPACITIES . Inspect the transmission oil cooler pipe connections at the radiator, the auxiliary cooler if equipped and the transmission for leaks.
