Alright kid07, I have a 03 WJ and the cooler is in the radiator for mine, the only thing that confuses me is that the line that has that bulky adapter (or bottom line under the oil pan) goes to the bottom of my cooler. Then flows upward then back down to return to the transmission. Does that make sense? Wouldn't that create a lot of unnecessary pressure to push fluid up?

And finally if i but the tow bumper on, should i go aftermarket cooler anyways?

Thanks!

I believe it flows upward so it does not all drain out when you park the Jeep, in conjunction with the check valve. If there was no back flow preventer, the check valve, all the fluid would run back and would have to refill the cooler every time you start the Jeep.

If you are going to be doing any towing or want to keep your transmission cooler, (which can never hurt to keep it running cooler), I definitely recommend a cooler.

First of all, thanks for posting this. I have a few question though. My 2002 4.0L is a bit different in that it has the transmission lines going to the drivers side of the radiator (cooler built into radiator). From what I've read on this thread, the trans fluid comes from the trans to the bottom of the rad/cooler to the top of the rad/cooler then back to the trans.
Is this correct?
If this is correct then the only trans line I will splice my cooler into would be the one WITHOUT that check valve on it?
Also, could someone post pics of any "test ports" on the transmission in order to hook up a trans temp gauge?
Just want to be sure, since I have very limited time to work on my Jeep.
Thanks dudes.

If you follow the same procedure you should be pretty good to go. You can check the flow the same way as I did by putting it in N for a half second and seeing where fluid comes out. Make sure you have a quart or two of transmission fluid to fill it up when you are done.

As for routing the lines and flow, it should all be in the first post.

I don't have a temperature gauge for the transmission fluid.

I just installed mine. Thanks for the tips Michael. I routed mine a bit different (Transmission --> Aux Cooler --> Factory Cooler --> Transmission). Here's my write up in my build thread with a bunch of pictures if anyone is interested: WJ Transmission Oil Cooler Install

I have a 2003 Overland. I could be wrong, or my memory is flawed, but I could swear that I have a transmission cooler on my Jeep already. With the fan shroud and the skid plate in the way, it's hard to get a good look, but I wasn't looking for it the other day. I was checking for a freon leak, but I remember seeing a skinny, silver/aluminum, cooler in front of my condensor, which is in front of my radiator. I have the tow package. I will have to go outside and take another look, maybe take pictures, but I could swear that is the way it is set up. I did not check to see where the lines go, like I said, I was looking for something else.

Take some pictures and post them and we'll help you out! There are multiple variations of transmission cooler locations and even factory auxiliary coolers on the WJ's

No, I was wrong. What I thought was a transmission cooler is a power steering/hydraulic cooler. I can see one line coming from the PS pump and the other line going into the steering box. I had my work clothes on, so I didn't slide under the car,. I assume my transmission lines go into the bottom of the radiator.
The PS cooler is about the third of the size of the condenser and sits, attached to the upper passenger side of the condenser, in front.

That is for the 4.0

I canabalized the hydraulic fan and PS Pump cooler from a 02 WJ with the 4.7

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.

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.
