Trans Oil Cooler Line Replacement
What is a transmission oil cooler line?
Transmission coolers are heat exchangers that remove excess heat from the transmission fluid. There are several designs, many are built into the vehicle's radiator.
How does the transmission oil cooler line work?
The transmission cooler lines carry transmission fluid back and forth between the transmission, and an external or radiator integrated cooler. They are often part or wholly metal, and screw in the transmission and transmission cooler at either end. The transmission fluid starts in the transmission, where work performed generates heat. It is then pumped to the transmission cooler where it sheds excess heat, and then returns back to the transmission. Heavy duty applications such as high performance vehicles, off-roaders, and tow-vehicles often utilize this system.
