WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The automatic transmission fluid cooling system consists of:
- an in-tank fluid cooler inlet tube.
- a non-repairable in-tank radiator transmission fluid cooler.
- an in-tank fluid cooler outlet tube.
- separate fluid cooler hoses.
- an oil-to-air (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.
For fluid cooler flow testing and backflushing and cleaning procedures, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - TORQSHIFT article.
