Transmission Fluid Cooler Flow Test

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The transmission linkage/cable adjustment, fluid level and line pressure must be within specification before carrying out this test. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS article for adjustments.
  1. Remove transmission fluid level indicator from transmission fluid filler tube.
  2. Place funnel in transmission fluid filler tube.
  3. With the vehicle in NEUTRAL, position it on a hoist. Refer to JACKING AND LIFTING article.
  4. Remove the transmission fluid cooler return tube (top fitting) from the fitting on the transmission case.
  5. Connect one end of a hose to the transmission fluid cooler return tube and route other end of the hose up to a point where it can be inserted into the funnel at the transmission fluid filler tube.
  6. Remove the safety stands and lower the vehicle. Insert end of hose into the funnel.
  7. Start the engine and run it at idle with the transmission in NEUTRAL.
  8. When transmission fluid flows from the hose in a steady stream, a liberal amount of transmission fluid should be observed. "Liberal" is about 1L (1 qt) delivered in 15 seconds. If a liberal flow is observed, the test is complete.
  9. If the flow is not liberal, stop the engine. Disconnect the hose from the transmission fluid cooler return tube and connect it to the converter outlet fitting (bottom fitting) on the transmission case.
  10. Repeat Steps 6 and 7. If flow is now approximately 1L (1 qt) in 15 seconds, refer to Transmission Fluid Cooler Back Flushing and Cleaning . If the flow is still not approximately 1L (1 qt) in 15 seconds, repair or install pump and/or converter.

    11. For the installation of new transmission fluid cooler or tubes, refer to TRANSAXLE/TRANSMISSION COOLING article.
