Transmission Fluid Cooler - Backflushing/Cleaning - Automatic Transmission

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When internal wear or damage occurs in the transmission, metal particles, clutch plate material, and band material can travel into the torque converter, the fluid cooler tubes, the in-tank transmission fluid cooler, and the oil-to-air OTA transmission fluid cooler. 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.

Clean the contaminants from the transmission fluid cooling system. Carry out the following:
- Carry out transmission fluid cooler, backflushing and cleaning to remove the contaminants from the cooling system.
- Carry out the transmission fluid cooler flow test to test for adequate flow through the cooling system. Refer to AUTOMATIC TRANSMISSION - 4R100 and AUTOMATIC TRANSMISSION - TORQSHIFT .
