4x4 Transmission Coolers

4x4 transmission coolers protect your vehicle’s transmission from heat. The most common cause of transmission failure is due to overheating of fluid. We offer aftermarket transmission coolers to prevent that from happening. 

Transmission overheating is often due to vehicles having unequipped engines for the conditions the vehicle is being used. When extra strain is placed on automatic transmissions additional transmission fluid is required to lubricate the moving parts. Since 4WD vehicle owners often push their vehicles to the limit – driving in rough terrains, hot conditions, or carrying and towing heavy loads – it’s important to ensure your vehicle is up to the task. 

We recommend investing in a transmission cooler if you carry extra cargo or passengers, drive a lot in stop-and-go traffic, or regularly drive off-road or in extreme weather conditions. Our transmission coolers help protect against corrosion, keep the transmission cool, and support better energy transfer. 

The transmission cooler works by making the fluid flow to the cooler. Air flowing over the cooler dissipates the heat and cools the fluid flowing through it. The cooled transmission fluid goes back to the transmission through the return line. It is a continuous process that is designed to lower the fluid temperature better than the stock radiator.
