Is this overkill for a transmission cooler?

I'm gonna pick this cooler up from amazon and wanted to get some opinions as to whether or not it's too big. Size is 3/4 inch x 11 inch x 11-5/8 inch. I live in Vegas and it's hot as hell here in the summer. Figured this couldn't hurt. Other question is will this take up too much space in front of the radiator?

size should be fine. will not be an issue in front of the radiator, I sat mine in the middle just up a bit form the bottom.

getting the cooler inside the grill to mount it will be the most challenging part of the installation. there isn't a lot of space to shove something in there, unless you pull the whole grill/condenser/radiator assembly apart.

You live in one of the hottest locations in the country, there is no such thing as overkill where cooling is concerned.

Instead of a passive type of cooler, I'd instead save my $$$ and get one with a thermostatically controlled fan. Auto transmissions in your part of the country need all the help with cooling they can get.

I live/wheel in the desert and this is what I installed... http://www.wranglerforum.com/f5/keep...er-110676.html

That was the plan, pull it all apart.

I was just wondering whether the tranny will get up to operating temperature with that big of a cooler. Jerry, the one you suggested is too technical for me to install and a bit pricey. Mine is just a daily driver that doesn't see too much trail time.

No such thing as overkill when talking about cooling a transmission. I have a cooler that is rated for a motor home on my Jeep.

Its fan only turns on when the ATF is too hot, it certainly will not prevent the transmission from warming up. The style cooler I installed, other than needing a simple source of 12 volts, is actually easier and faster to install than one that mounts in between the grill and radiator. That kit is made specifically for a Wrangler which greatly simplifies its installation.

It is my understanding (from advice gathered here) that if you run your trans line to the cooler first, then to the radiator, then back to the trans, you *should* keep the temps within the parameters of the electronic monitor device in the transmission.

Tranny cooler should go after it goes through the stock radiator cooler.

Right, from the cooler then back into the transmission.

Is the V shaped bar in front of the a/c condenser needed for grill support? I need to mount the cooler in front of the condenser, but the bar is in the way.

I want to say it is about half the size of the radiator. It was hard to get in there, but it was only once.

Well, I got it in there and ran the lines. It only took about 45-60 minutes from start to finish. I didn't even have to take the grill off, I just unhooked the radiator, condenser and V bracket and it just slid right in with a little effort. It looks like it might be too big and cover up too much of the radiator so I'll see if it affects engine cooling over time. It better do it's job...haha

The Hayden Rapid-Cool Trans Cooler #679 that I bought states that it can be mounted in the vertical or side position. Which one is best for optimal cooling? I've seen other posts that state the side mount is best to eliminate air bubbles?

I am not sure where your ports are from the pic, but I believe the cooler should be mounted with the ports on the side and the inlet port on the bottom and the outlet on the top.

I don't think this is right (even if the instructions say so).

Looks Good

Looks good to me. Make sure you add a little more fluid to make up for the extra volume you added.

It mounts better with the tubes in the down position, but I don't know if that will affect the cooling properties or not. Some have said that air can't escape with it setup this way. Can anyone chime in on this and tell me how yours is mounted? Thanks!

This is true. Ports should be mounted on the side so you don't have issues with trapped air. Inlet on the bottom, outlet on the top so the fluid is forced up and any air would be forced out. You can check PSC website for a technical mounting diagram.

I mounted my tranny cooler sideways, inlet on the bottom, outlet on top...so air can escape.

Do y'all have any pics of your mounts? I'm trying to get some ideas because it doesn't mount very good going sideways with that V bar in the middle.

I also would love some pics if you guys can get them together. I got this today:
And want to make sure I know what I am doing before cutting tubes and mounting.
If I cut the trans outlet tube, it wont release fluid right? I am pretty sure it has to be on to run fluid through the tubes

Has anyone noticed where both of the factory OE tranny cooler ports are? On the bottom.

Jerry, which port is the outlet for the tranny?(AKA the line I want to tap into). I am pretty sure it is the line on the bottom passenger side, but not positive and am having trouble finding the answer online. I really don't want to cut the wrong one.

For your '05, it's the driver's side. 2002 and older use the passenger side.

When I swapped trannys last year and mounted a cooler, I put my ports on the bottom and haven't been struck by lightning yet, so I guess I didn't sin too bad!!
