Transmission Cooling
Transmission CoolingAutomatic Transmission
The automatic transmission fluid cooling system consists of:
^ an in-tank fluid cooler inlet tube.
^ a non-repairable in-tank transmission fluid cooler.
^ an in-tank fluid cooler outlet tube.
^ separate fluid cooler hoses.
^ an OTA transmission fluid cooler.
^ a fluid cooler return tube.
^ hose clamps.
^ a remote mount fluid filter and bracket.
The transmission fluid flows from the transmission front fitting, to the in-tank transmission fluid cooler, to the OTA transmission fluid cooler, and returns to the transmission rear fitting.
CAUTION: Do not attempt to backflush and clean the OTA transmission fluid cooler.
Install a new OTA transmission fluid cooler as part of a transmission overhaul or exchange. Failure to follow these directions can result in transmission damage.
