Automatic Transmission: Notes
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 4R100 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, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 4R100 or AUTOMATIC TRANSAXLE/TRANSMISSION - TORQSHIFT .
