Transmission Cooler: Description and Operation

Introduction





The transmission fluid cooling system maintains fluid temperature within specified limits.

Component Descriptions
The transmission fluid pipes:
Transfer fluid from the transmission to the cooler under the action of the hydraulic system pump.
Return the cooled fluid from the cooler to the transmission.
The transmission fluid cooler:
Is a plate type made from aluminium.
Is mounted in the engine cooling radiator right-hand end tank.

Overheating Protection
If the engine coolant or transmission fluid temperatures exceed their predefined limits, the transmission control module locks the torque converter clutch. By reducing slip, this minimizes the amount of heat transferred to the engine cooling system from the transmission fluid.
