Transmission Fluid Cooler: Notes
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.
CAUTION:
Whenever a transmission has been disassembled to install new parts, the cooler bypass valve (CBV) and transmission fluid cooler lines must be cleaned and backflushed. Install a new oil-to-air cooler (OTA).
NOTE:
Cleaning and backflushing the transmission fluid cooling system and installing a new OTA cooler along with following all the normal cleaning and inspection procedures during disassembly and reassembly will keep contamination from entering the transmission, causing a repeat repair.
When internal wear or damage has occurred in the transmission, metal particles, clutch plate material, or band material may have been carried into the torque converter and transmission fluid cooler. These contaminants are a major cause of recurring transmission troubles and must be removed from the system before the transmission is put back into use.
