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
^ an oil-to-air (OTA) fluid cooler inlet/outlet hose assembly for the 4RI00 transmission
^ separate fluid cooler hoses for the TorqShift transmission
^ an OTA transmission fluid cooler
^ a fluid cooler return tube
^ hose clamps
^ a remote mount fluid filter and bracket for the TorqShift transmission
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.
For fluid cooler flow testing, and backflushing and cleaning procedures.

Manual Transmission
The manual 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 return tube
The transmission fluid flows from the transmission bottom fitting to the in-tank transmission fluid cooler and returns to the transmission through the top fitting.
For fluid cooler flow testing, refer to Transmission Fluid Cooler Flow Test - Manual Transmission. For fluid cooler backflushing and cleaning, refer to Transmission Fluid Cooler Backflushing and Cleaning - Manual Transmission.
