to be honest every 99+ 4.0 owner ought to think about getting the condenser assembly for the later model WJ's and the tubing (junk yard or dealer) and use that as the Aux Trans cooler. To me it's a better setup but will cost some money to install it.

No tranny fluid runs through my condenser. I have an 04 H.O. Power steering for sure. I replaced my condenser today and lost a bunch of power steering fluid. Busted the o-ring. Doh! Started it up and lost almost the whole quart. Wheel would not budge. The power steering pump hated that! Lots of noise. I thought I was going to have to replace the pump but after I added 3/4 of a quart of power steering fluid and checked everything the noise went away. It took a few trips around the block. I will probably end up replacing the pump anyway. I think I may have done some damage but it seems to be quiet now except on full lock, which to me is normal. I will keep an ear out for that terrible power steering pump noise.

Yes for the 4.7 that is the only trans cooler. And I'm pretty sure its the same for all V8's with the hydraulic cooling fan.

86cj74.2L The only thing I can figure out is they kept the same AC condensed and if you had the 4.7 the aux cooler portion was for the powersteering fluid. If you had the 4.0 it became the trans cooler. And the 42 behind the 4.0 needs all the help it can get.

Both 04's I have have the tow package and no extra cooler which also falls in line with a how to tow PDF from Chrysler that says no aux cooler needed.

snobrdrkid07 So from what I have gathered, in the 2004, 4.0, WJ, ONLY it uses the radiator in it's entirety for the the coolant. The splits the AC condensor in half for the AC system and the transmission fluid cooler.

There weren't any oil coolers on the WJ's to my knowledge.

86cj74.2L It is quite interesting that jeep uses the AC condenser aux cooler for the trans on the 4.0. If I understand correctly that split AC condenser was a 2004 thing only. The Aux cooler portion is quite big.

And another example of auto manufactures getting it right for the last model year.
07-31-2013 06:00 PM
snobrdrkid07 I'll agree to that. This thread was originally for the 2004 WJ 4.0's
07-31-2013 05:52 PM
86cj74.2L Its too confusing saying it should be this or that. They changed over the years.

As an example my 04 Laredo with the 4.7 has no aux trans cooler and the top 1/3 of the AC condenser is the powersteering cooler.

The transcooler is on the passanger side tank on the radiator. So it goes fan, rad, condensor and infront of that biased
toward the drive side is the Power steering cooler.
The picture I posted above is the factory Power Steering Cooler on the 4.7's.

The Factory Aux Trans cooler on the 4.7 is on the passanger side and the factory power steering cooler is on the driver's side.

The picture below is the stock aux cooler setup on a loaded out 4.7.

snobrdrkid07 This is what the factory power steering cooler looked like...
