How to install transmission oil cooler kit

This installs on the radiator itself and has a relay that feeds the power to the fan.

I also ordered a remote thermostat that would be adjusted to turn the fan on at 175 degrees (or so) and off again. After a quick email to the seller, I received a package that came with all the mounting hardware including springs to absorb vibration caused by the road and the engine. When the fan arrived, it was missing several critical installation pieces. WeвЂ™ll see what the readings are this season and make changes accordingly.ДЄfter researching online I selected a 9вЂі 12 Volt 80 Watt Fan that would move enough air to make a dent in the temperature. The down-side is getting the transmission fluid up to operating temperature in colder weather. I COULD remove the plumbing for the auxiliary cooling loop in the radiator and likely reduce the starting temperature a little since the transmission fluid wouldnвЂ™t get heated by the engine coolant flow. I have seen 250 degrees on a long hill, mostly due to airflow issues. So, shooting for an average temperature of 200 degrees seems reasonable. Wow, 40 Miles! IвЂ™d hate to have to change the transmission fluid that often! Personally, I can accept every 25,000 miles.

This chart shows how the life is shortened with temperature increases: Some manufacturers state you can get 100,000 miles from the fluid IF it remains at 175 degrees or below. Most manufacturers of transmission fluid say, if the fluid gets above 300 degreesВ Fahrenheit for any length of time permanent damage could be done to the transmission itself. For some reason they decided NOT to add an electric fan on this supplemental cooler. My Aero Cruiser had the former and a previous owner added the latter. Sometimes itвЂ™s as вЂњsimpleвЂќ as a few extra pipes inside the engine coolant radiator and sometimes itвЂ™s a separate radiator entirely. Many RVs have some kind of transmission cooler already installed. Common Sense, right? Pull a heavily loaded RV up a long hill, sometimes with a trailer or toad behind, and the transmission temperature will climb. The harder the transmission is working the hotter the fluid gets. LetвЂ™s talk a bit about automatic transmission temperatures in general. I decided that adding a fan and maybe a thermostat to automatically turn it on and off when needed would be a good idea. On a recent trip driving through some mountainous terrain, I noticed my transmission temperatures were higher than IвЂ™d liked.

The fluid is cheap, your transmission isnвЂ™t. If you вЂњcookвЂќ your transmission oil, bad things will happen. At some point in itвЂ™s life, my coach had a supplemental transmission oil cooler installed.
