Transmission Coolers

Upon exceeding normal operating temperatures, oil begins to lose viscosity and lubricating properties, which leads to rapid breakdown and deterioration. You can prolong the engine’s life and extend the life of your oil by using a transmission cooler. Whenever an engine is rebuilt or after a catastrophic failure, the transmission cooler should be replaced. Contact us for our Cat Aftermarket transmission coolers.
