Where do you mount an external transmission cooler?
Mounting a transmission cooler is typically best in front of the air conditioning condenser so it gets ample air flow. Mounting here provides significant air flow which will help keep temperatures low. In addition, having the right parts to install a transmission makes the process easier.
How do external transmission coolers work?
How Does a Transmission Cooler Work? Fluid heated by the transmission, engine, or power steering pump flows to the cooler. Air flowing over the fins of the cooler carries away heat and cools the fluid flowing within the fins. The cooled fluid is routed back through the transmission via the return line.
What do you need to know about transmission cooler installation?
The below transmission cooler installation diagram shows the transmission fluid flow direction and how the fluid will be routed through a new external cooler. You will need to determine which line is the return for the transmission.
