Inspection and Verification
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When internal wear/damage occurs in the transmission, metal particles, clutch plate material and band material can travel into the torque converter, the fluid cooler tubes, the intank transmission fluid cooler and the auxiliary transmission fluid cooler, if so equipped. These contaminants are a major cause of recurring transmission concerns. To prevent future concerns, remove these contaminants from the cooling system before placing the transmission back into use. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 4R70W/4R75W
or AUTOMATIC TRANSAXLE/TRANSMISSION - 4R70W/4R75W
for fluid cooler flow testing, backflushing and cleaning, torque converter cleaning and inspection, and flushing.
- Visually inspect for obvious signs of mechanical damage, incorrect component installation and system leaks. Repair as necessary.
- Install a new or remanufactured radiator when fluid is found leaking from the in-tank transmission fluid cooler. For additional information, refer to ENGINE COOLING .
- Install a new O-ring when transmission fluid is found leaking between the radiator transmission oil cooler and the transmission oil cooler fitting (not the cooler line into the fitting). For additional information, refer to COMPONENT TEST .
- Install a new auxiliary transmission fluid cooler if there is leakage from the fluid cooler. For additional information, refer to AUXILIARY TRANSMISSION FLUID COOLER .
- If the fault is not visually evident, GO to SYMPTOM CHART .
