As good as top-quality synthetic lubes are, sometimes the transmission fluid just isn’t enough to keep everything cool. There are times when the fluid temperature can exceed the maximum range of 160 to 200 degrees, and when this happens the fluid begins to burn. This decreases the amount of fluid running through your transmission, which in turn can seriously damage all of the important moving parts within the transmission. Installing a transmission cooler is an extra precaution against overheating your transmission, and many people decide to use them in not only tow vehicles, but classic trucks and hot rods. As you can see, transmission coolers come in many different shapes and sizes, and there are things to consider when choosing one.
