Transmission Fluid Cooler: Notes
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:
Prior to this test, the in-line service filter (if equipped) will need to be removed. Failure to remove the in-line filter may result in an incorrect reading/diagnosis during this test.
CAUTION:
Whenever a transmission has been disassembled to replace worn or damaged parts, the cooler bypass valve (CBV), all transmission fluid coolers (in tank and auxiliary), and transmission fluid cooler lines must be cleaned and backflushed.
NOTE:
Cleaning and backflushing the transmission fluid cooling system, along with following all the normal cleaning and inspection procedures during disassembly and reassembly, will keep contamination from entering the transmission and 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.
