Transmission Cooling: Notes

The transmission fluid cooling system consists of:

• transmission fluid cooler inlet and outlet tubes.
• an in-tank transmission fluid cooler inlet tube.
• a non-repairable in-tank transmission fluid cooler.
• an auxiliary transmission fluid cooler inlet tube (HD).
• an auxiliary transmission fluid cooler (HD).
• an auxiliary transmission fluid cooler return tube (HD).

The transmission fluid flows from the transmission to the in-tank transmission fluid cooler, to the auxiliary transmission fluid cooler and returns to the transmission.
