I'm going to be running 35's by the end of the year, probably on stock gearing for a while (not that I'll be driving it much like that), if that makes any difference...no threadjack intended. There should be a sticky on these tranny coolers!

It's already got the OEM electric fan pulling on the back side. If you're concerned you could wire the OEM electric fan to be able to turn it on when you think you're putting the transmission through it's paces.

It'd be interesting to see a way to alter the wiring of the OEM fan, so that it comes on when the tranny temp reaches a certain temperature. That would be ideal!

I mounted the cooler in front of the electric fan to pull more air across it.

Whoops lol. Sorry my bad.

I installed my cooler in front of the electric fan too, I also hooked up a trans temp gauge so I can watch my aw4's temperature, and if I need to, I can turn on the fan to help cool down the tranny fluid little more quickly.

I reckon it would be easier to just throw a manual switch in there. One less sensor to worry about, anyhow. I plan on mounting my cooler the same way.

I put my tranny cooler in front of the mechanical fan, that way it's always getting air pulled through it. Trying to keep it as cool as possible at all times.
