A transmission cooler is a part of your car that keeps the transmission cool. It does this by moving heat from the transmission oil to the air. This keeps the transmission from getting too hot, which can hurt it.
Most of the time, transmission coolers are put in front of
the radiator. They can be cooled by either air or water. Transmission coolers
that use air to cool the fluid use fans to move heat from the fluid to the air.
A radiator moves heat from the transmission fluid to the cooling in a
water-cooled transmission cooler.
The transmission cooler is a key part of the cooling system
in your car. They keep your transmission running well and keep it from getting
too hot. If your transmission cooler is broken or not working right, it could
hurt your transmission in a big way.
