Flow Test
WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
Important : The Flow Test must be performed after the flush to ensure that all flushing solution and water is removed from the oil cooling system.
- Disconnect the hose from the oil cooler pipe. Connect the oil cooler feed pipe, top connector, to the transmission for normal flow.
- Clip the discharge hose (1) to an empty oil container.
- Confirm the transmission is filled with automatic transmission fluid. Refer to Fluid Capacity Specifications for the correct automatic transmission fluid capacity.
- Start the engine with the transmission in PARK range and run for 30 seconds after fluid begins to flow from the discharge hose (1). A minimum of 1.9 L (2 quarts) must be discharged during this 30 second run time.
- If the fluid flow meets or exceeds 1.9 L (2 quarts) in 30 seconds, connect the oil cooler feed pipe to the front connector on the transmission.
- If fluid flow is less than 1.9 L (2 qt) in 30 seconds, perform the following diagnosis:
- Disconnect the J 35944-A discharge hose (1) from the oil cooler return pipe.
- Disconnect the oil cooler feed pipe at the radiator.
- Connect the J 35944-A discharge hose (1) to the oil cooler feed pipe, radiator end.
- Clip the discharge hose (1) onto the oil drain container.
- Start the engine with the transmission in PARK range and run for 30 seconds after fluid begins to flow from the discharge hose (1). A minimum of 1.9 L (2 qt) must be discharged during this 30 second run time.
- If the amount of transmission fluid flow remains less than 1.9 L (2 qt) in 30 seconds, inspect the oil cooler feed pipe, top connector, for restrictions or damage. If no condition is found with the feed pipe, inspect the transmission.
