Mountaineer RWD V6-4.0L (2008)
Transmission Cooler: Component Tests and General Diagnostics
Transmission Fluid Cooler
CAUTION: Whenever a transmission has been disassembled to install new parts, the transmission fluid cooler and transmission fluid cooler
tubes must be cleaned and backflushed. Use a torque converter/oil cooler cleaner.
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 contaminants 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.
