I just bought an RPM trans and a trans cooler from them with a fan......I would have bought the tru cool but I need a cooler with a fan and a temp switch. The set up is a 3200 stall and I get stationed out in the desert a lot where it is 120 degrees....

Have any of you guys wired this up before? Key hot or on a switch? What have you guys done to power an electric fan on a trans cooler? I was thinking about just cruising some of the electric fan threads for some wiring ideas, I wanted to ask here first......

Seriously thinking about ditching my budy's wedding that I have to go to on Saturday to put this bad boy in! HA HA! Staring at the trans in the crate is KILLING ME!

 

You can just find a ignition switch power in fuse box that's what I did for my efans

 

Definitely ditch the wedding.. Get that thing in and post up some pics along the way.

For the wiring, it really just depends on what you want out of it. You can have it run all the time when your driving buy just using a key hot source and a solid ground. Or a switch isn't a bad idea if you will remember to turn it on when needed. I've never had a fan on a tranny cooler but when I had aftermarket cooling fans for the radiator, I had them running all the time. I found that the temp switch wasn't very consistent.

There isn't a pin in the pcm that would allow you to run the fan based on tranny temps. So the efan threads won't do you any good.

 

You can put a 'T' in the cooler line from the transmission.
-6 -6an and a -4 an on the top side with a bushing to reduce it from -4an to 1/8" NPT and put your thermostat in there.

Trans temp gauge and wire in an override switch incase the Tstat fails.
