Perma-Cool Heavy-Duty Transmission Coolers

4.33 out of 5 stars 15 Customer Reviews

Perma-Cool heavy-duty transmission coolers are perfect for tow vehicles or transmissions equipped with high stall-speed converters. They are easy to install and feature a rugged 1 1/2 in. thick design to control chronic fluid overheating and breakdowns in high-heat applications. These coolers are available in a variety of sizes, with a large array of tube-pass variations. They have oversized 5/8 in. diameter tubes with Turbulator cooling fins for maximum heat transfer, and durable mounting brackets for a secure attachment. Unless otherwise noted, the coolers include hose, fittings, and mounting hardware.
