Question JK Auto Tranny Cooler ?

Even though they came with the stock cooler in front of the radiator, how many are installing a backup cooler for the autos? I have read some stuff on other sites saying the tranny temp is dropping from 220 normal driving with big tires down to like the 170-180 range with the backup coolers. I went and got one and kinda been draggin feet on the install, I think it sounds good anyways.

I finally picked mine up Saturday and plan to have it in by the weekend. It's an Imperial plate style by Hayden, similar to this one.

I say if you're gonna go, go large. I installed the B&M 70297. I like having the extra cooling fan in there for when it gets really hot on the slow crawls.

Smile JK Auto Tranny Cooler

I installed a Derale 21" Heat Sink Coller in the front of the condenser. It holds about 1 qt. transmission fluid.
Prior to installation, I checked transmission pan temperature with a laser thermometer, 60 degree day in AZ, 20 mile trip, the temperature averaged 178 degrees.
After cooler install, similar driving conditions, average transmission pan temp, 148 degrees.

I believe it's 180 degrees. According to the FSM, the dipstick full mark is with the transmission at "normal operating temperature of 180 degrees".

This looks like a good idea. I've seen examples of these with out the fans, has any got details of the installation of one with the fan?

I have the Hayden 404 Trans Cooler and it works great for me! It was pretty cheap. I don't think I need one with a fan.. Just more problems with water!!
