Inspection and Verification
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 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 (7A095), 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-4R100
or AUTOMATIC TRANSAXLE/TRANSMISSION-4R70W
for fluid cooler flow testing, backflushing and cleaning, torque converter cleaning and inspection, and flushing. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION-4R100
for cooler bypass valve (CBV) assembly (7H322) cleaning 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 intank transmission fluid cooler. For additional information, refer to ENGINE COOLING .
- 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 .
