Hayden 516 High Performance Transmission Oil Cooler Heavy Duty Black Universal

Hayden 516 High Performance Transmission Oil Cooler — Heavy Duty Black Universal

Protect Your Transmission From The #1 Cause Of Automatic Transmission Failure — Heat

Automatic transmissions run hot — and when you're towing a trailer, hauling heavy loads, driving in stop-and-go traffic, or running a performance build, the stock radiator-mounted cooler often cannot keep fluid temperatures in a safe range. The result is degraded fluid, accelerated wear, slipping gears, and eventually, complete transmission failure.

The Hayden 516 is a heavy-duty, high-performance transmission oil cooler engineered to handle these exact demands. With a towing rating of up to 10,000 lbs and compatibility with Class A motorhomes, this is one of the most capable auxiliary transmission coolers in Hayden's lineup.
