Installation Instructions for a Transmission Cooler on a 1990 Mazda Miata

Expert Reply:

Transmission coolers are universal fit items so there really are not any vehicle specific installation guides available. They are easy to install, even with the most basic mechanical ability levels. I will briefly describe the process and I will send a second email with a general guide.

The first thing you need to do is find a spot in front of your Miata radiator where you want the transmission cooler to sit. The dimensions of the transmission cooler are 11 inches long, 4 inches tall and 3/4 inch thick. Measure the space where you want mount the cooler and make sure it will fit. The mounting hardware works like zip-ties. You would put the soft pads between the radiator and the transmission cooler, and feed the rods through the mounting holes on the transmission cooler and through the fins on the radiator and snug everything up with the buttons.

Then you will need to locate the feed and return lines from the transmission and connect them to the radiator. Your vehicle owner manual should explain where those lines can be found.
