Transmission Fluid Cooler

Transmission Fluid Cooler

Caution: Whenever a transmission has been disassembled to replace worn or damaged parts or because the main control valve body sticks from foreign material, the main control valve body, transmission fluid cooler and fluid cooler inlet tube and fluid cooler tube must be cleaned and flushed using Torque Converter/Oil Cooler Cleaner. Under no circumstances should an attempt be made to clean the torque converter by hand agitation with solvent.

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.
