Quick Answer: How big of a transmission cooler do I need?

Transmission coolers are rated by their gross vehicle weight or GVW, and this can go from as little as 10,000, all the way up to 40,000 or more! Based on the transmission cooler GVW chart shown below, the optimal transmission cooler should be at least 20,000 depending on the tow capacity.

Can a transmission cooler be too big?

Do I really need a transmission cooler?

For every 20F degree drop in transmission fluid temperature, you can expect to extend the fluid and equipment life, thereby extending the life of the vehicle. That’s why it is very important to have a quality transmission cooler, and more importantly, to have it professionally installed.
