Protect your reputation, and your customers’ transmissions, by installing a transmission cooler during a rebuild. The ideal operating temperature for the transmission and fluid is between 160 and 200 degrees Fahrenheit. Transmission fluid cannot be over-cooled, so adding an aftermarket cooler would be a good idea as factory coolers can be inadequate for towing applications.
Use a Transmission Cooler if you:
Tow boats, trailers or fifth wheels
Drive in stop-and-go traffic
Climb steep grades
Drive in hot weather
Preserve the life of your transmission and improve towing performance with a transmission cooler. Protect your vehicle's warranty or simply give your vehicle a boost with a simple to use addition to any towing set up. Push on fittings and three mounting positions ensure a hassle-free installation, while varying performance levels allow you to match the transmission cooler to your specific towing needs.
Transtar carries adapters that allow you to bypass the OE cooler / warmer that is on the transmission for use with a stand alone cooler.
