Transmission Cooling

Transmission Cooling

The transmission fluid cooling system, without an auxiliary transmission fluid cooler, 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 cooling system, with an auxiliary transmission fluid cooler, consists of:

- an in-tank fluid cooler inlet tube.
- a non-repairable in-tank transmission fluid cooler.
- fluid cooler hoses.
- hose clamps.
- an auxiliary transmission fluid cooler.
- a fluid cooler return tube.

The transmission fluid flows from the transmission (front fitting for TorqShift(R), bottom fitting for the 4R70E/4R75E), to the in-tank transmission fluid cooler, to the auxiliary transmission fluid cooler (if equipped) and returns to the transmission (rear fitting for TorqShift(R), top fitting for 4R70E/4R75E).

For the Transmission Fluid Cooler Flow Test and Transmission Fluid Cooler Backflushing and Cleaning procedures, refer to Transmission Control Systems. Testing and Inspection
