Transmission Cooler: Application and ID
TRANSMISSION AUXILIARY AIR COOLER
An auxiliary transmission cooler is required equipment on all Cherokee and Wagoneer models equipped with a heavy-duty 1837 kg (4050 lbs)
trailer towing package. The auxiliary cooler augments the transmission cooler in the radiator lower tank to prevent fluid overheating during
heavy-duty operation. The auxiliary cooler is located behind the grille. It is mounted on the grille face panel assembly in front of the A/C
condenser and radiator.
If it becomes necessary to overhaul the transmission to correct a malfunction that generated sludge or heavy accumulations of metal particles or
friction material, the auxiliary cooler and cooler hoses must also be flushed thoroughly along with the radiator cooler. Refer to Flushing Oil Cooler
and Cooler Lines.
See: Fluid Line/Hose/Service and Repair
If the auxiliary cooler must be removed and installed for servicing or for access to another component, refer to Auxiliary Air Cooler Removal and
Installation.
