The transmission cooling system is vital to any transmission. It circulates the hot fluid away to the radiator via cooler lines and returns the cooled fluid back to the transmission. A loss of fluid leading to an overheated transmission can be devastating as the system loses its ability to cool.
Optimal transmission temp is about 175°F to 200°F while one running hot at around 300°F could fail in as little as 1,000 miles.
That is why it is important that any car owner hoping to keep their car’s transmission healthy will need dependable, leak-tight transmission cooler to carry that fluid to and from the cooler.
