Description And Operation
DESCRIPTION
The transmission heat exchanger is located on the side of the transmission near the transmission fluid cooler tubes.
OPERATION
This vehicle features an active transmission warm-up system with an oil-coolant heat exchanger on the transmission. The hoses are connected to the engine cooling system. The engine cooling circuit has both a three-way valve for coolant and a bypass valve in the transmission oil cooling circuit so the transmission oil can be warmed up more quickly from a cold start, which reduces parasitic loss from the drag of the spinning gears. If the transmission oil is getting too hot, such as during towing, the bypass valve setup directs oil from the heat exchanger and into the transmission cooler in the front-end cooling module.
