Product Description

With automatic transmissions, performance and longevity are reliant upon temperature. Reducing internal heat eliminates the chance of overheating fluids, which causes viscosity breakdown and transmission strain. Therefore, a cooler running trans lasts longer. Help protect your transmission on the street and at the strip with this complete transmission cooler kit. Includes all the necessary adapters, fittings, and hoses you will need for installation.

Works well, necessary when upgrading coolant system. Wish I would have know when ordering mishimoto coolant setup. Took two trips to the mechanic. Please add this opgrade as a necessary component to mishimoto coolant system. Avoids conflict.

This worked great on a 3.7 Q50. I was able to mount it to the bumper bar behind the bumper and cut out a couple of small holes in the radiator shroud to route the lines to the factory hard lines. I would recommend picking up two additional hose clamps to replace the factory ones as the kit comes with 2.

Not the greatest. Hoses are wrong size to fit on factory hardlines. I adapted connections to -6AN hose and everything worked great. Stilled needs to reevaluate the materials supplied in the kit. No complaints on actual cooler.
