I installed this Transmission Cooler on my 2004 Jeep Wrangler Rubicon TJ with an Automatic Transmission. The install was straightforward and simple. I would definitely recommend this product to anyone who has the 42RLE Transmission. This kit had everything. I did not have to purchase any additional parts to get the job done. Super simple install.

This item would not work on our vehicle. Despite being listed on Amazon as free returns, the seller charged for the return shipping by reducing the refund amount. I will update if they change their position and return the rest of the refund.

Works well, but does not fit on frame as advertised if you have a long arm kit. It is supposed to mount where the long arm mounts. As you can see in my photos I manufactured my own mount and mounted it inside the engine compartment on the passenger side. Consequently it made plumbing the unit much easier

The cooling of the radiator and fan is good and works well. Very nice components. A big HOWEVER is this is NOT a direct bolt in for a 2005 Jeep TJ. The TJ cooling lines are not clamped on like the instructions say but have quick disconnects. You will need to get adapter fittings to attach the one line to the main radiator cooler. Derale could proved this $5 part to make life easier but it's not included. You will need to buy one Hayden Oil Cooler Installation Kit HDN 397. This will allow you to keep your quick disconnect in the radiator and use this to hook up the 3/8 line to it.

Everything fits perfectly. I wish the cooler lines were a little longer but overall an easy install. The instructions say to look for a silver label on the fan that will tell you if the black wire is a ground or if it’s the power wire. THE BLACK WIRE IS THE POWER WIRE. if you use the black wire as the ground it’s going to be pushing air through the cooler and NOT pulling air through it. Overall love the product

What a great package,fits nice under the Jeep and was a fairly easy install. Added a temp gauge at the same time and it’s keep the transmission temps down even in the 110 degree Texas heat.

Fit great! Easy install! The fan negative and positive I read where backwards on some reviews online. I used a 9v battery to see which was the ground wire. The air should be sucked through the cooler. Great product over all though

Update after 7 years: Works well overall. However, the U-connector on the cooler return line began leaking, similar to another review I saw. Derale does not sell this replacement part outside the kit, so I'm going to try to cut off their crimped hose connections and clamp with hose clamps instead.Includes everything from zip ties to electrical wire. I have some side steps mounted to the frame near where this is supposed to mount, so mine had to be installed about 8" farther back than normal. Because of this, I had to extend one of the fluid lines. For a normal installation, the lines should be just the right length.I did run the electrical line to ignition-switched power with a relay, although I've heard good arguments to just use constant power from the battery (reliability, fewer wire splices and no relay to fail). The instructions do recommend an ignition-switched source, but I wouldn't recommend just tapping into a random circuit, as I'm betting this fan draws a few amps. Depending on what else is on the circuit, it might not provide enough power or blow a fuse. For that reason, I found an ignition-switched circuit and ran it into the engine compartment where I installed a new relay (not included). So the fan gets its power directly from the battery, but is switched on with the ignition.I've only heard it activate once so far, on a 95 degree day, with me "trying" to generate some heat in the transmission. I did have to roll down the window to hear the fan - it's not that loud like some others have said.
