The automatic transmission fluid cooling system consists of the following:
- Rear transmission fluid cooler tube, rear of transmission to quick connect
- Rear transmission fluid cooler tube, front of transmission to quick connect
- Quick connect secondary latches
- Front transmission fluid cooler tube assembly
- In-tank transmission fluid cooler
- Auxiliary Oil-To-Air (OTA) transmission fluid cooler
- Hose clamps
The transmission fluid flows from the front transmission fluid fitting on the transmission, through the rear transmission fluid cooler tube assembly, through the front transmission fluid cooler tube assembly, to the in-tank transmission fluid cooler, to the OTA transmission fluid cooler and returns to the rear transmission fluid fitting on the transmission.
NOTE:
Do not attempt to backflush and clean the Oil-To-Air (OTA) transmission fluid cooler. Install a new OTA transmission fluid cooler as part of a transmission overhaul or exchange. Failure to follow these directions may result in transmission damage.
For transmission fluid cooler flow testing and backflushing and cleaning procedures, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - TORQSHIFT article.
