Transmission Fluid Cooler Flow Test

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The selector lever cable adjustment, transmission fluid level and line pressure must be within specification before carrying out this test. Refer to Transmission Fluid Level Check under Preliminary Inspection . Refer to Line Pressure Test under Special Testing Procedures . For selector lever cable adjustment procedures, refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS article.
  1. Remove the transmission fluid level indicator from the transmission fluid filler tube.
  2. Place a funnel in the transmission fluid filler tube.
  3. Raise and support the vehicle.
  4. Disconnect the transmission fluid cooler return tube (rear fitting) from the transmission case.
  5. Connect one end of a hose to the transmission fluid cooler return tube and route the 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 supports and lower the vehicle.
  7. Insert the end of a hose into the funnel.
  8. Start the engine and run at idle with the transmission in NEUTRAL.
  9. Once a steady flow of transmission fluid (without air bubbles) is observed, remove the hose from the funnel and place the hose in a measuring container for 15 seconds. After 15 seconds, place the hose back into the funnel and turn the engine off. Measure the amount of transmission fluid in the container.
    Temperature Flow
    44°C (112°F) 236.6 ml (8 oz.) 15 sec
    78°C (172°F) 473.2 ml (16 oz.) 15 sec
    82°C (180°F) and up 1893 ml (64 oz.) 15 sec

    There is a temperature valve in the pump. Transmission fluid cooler flow rates will vary according to Transmission Fluid Temperature (TFT). The use of a scan tool will determine the actual TFT. If adequate flow is observed into the container, the test is now complete.

  10. If adequate flow is not observed, turn off the engine. Disconnect the hose from the transmission fluid cooler return tube (transmission inlet).
  11. Disconnect the transmission fluid cooler tube from the front case fitting and connect the hose to the case fitting (converter out) and repeat Steps 7, 8 and 9.
  12. If adequate flow is not observed from the transmission, look for a plugged or crushed cooler tube and/or fluid cooler. Refer to TRANSAXLE/TRANSMISSION COOLING article for diagnosis of the transmission fluid cooler.
  13. If adequate flow is still not observed, repair and/or installation of a new pump and/or torque converter may be required.

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