mounting trans cooler in the rear.

[wedge5]

I am looking at getting a trans cooler w/fan set up. I have a cooler mounted up front but was thinking about ditching that and mounting a new one in the rear of the car behind the tires. I also have a 10" fan that I could put on my old one. Either way I am looking at mounting one back there.

Any of you guys have some pics of your done this way?

I've seen it done and looks pretty cool but I always wonder about the cooling efficency back there. Atleast up front you get the air blowing on it. I also run a fan in front of mine for those very hot summer days.

A lot of the AH cars and the SS/GT cars are putting the trans cooler in the trunk. I guess the electric fan route is OK but just makes another thing that needs power to run. Much simpler to just mount on radiator and let incomming air do the job. On some of my cars I have just run a loop line with no cooler and that worked fine as well, I saw no difference in wear at tranny tear downs.

I wasn't going to run it in the trunk. Was going to mount it under the trunk floor.

Just a thought, I saw it on a few cars. Was told when I asked why they told me if the cooler burst then the fliud wouldn't get on the rear tires. Made sence to me and it also looked cool.

On another thought: What are you guys using for trans cooler lines? I ran new steel lines but they look kinda small to me. Was wondering if they were moving enough fluid?

 

[poppaj]

I use 6an braided steel. Mounting it in the rear under the car could be a problem if slicks throw a rock or something, it could punture the cooler and cause a leak.

same here, 6AN braided ..... 16 pass cooler w/elec fan in front of radiator .......

 

[moparstuart]

sure is a long way to be pumping fluid

True so True. I will just leave it where it is at, this way I wont have to re-route things.

What fitting are you putting in the trans? I have the stock ones. Do they make a -06 fitting that would fit into the trans ports. If so where do I get them, local speed shop?

1/4"npt male to 6an male

 

[wedge5]

Sweet. I am going to do that soon.

My buddy runs his in the back on his stock car, runs it dirt and oval and never had a rock bust it. Does a good job too because running in second gear at speed generates a lot of heat.

1/4"npt male to 6an male

Thats the WRONG ANSWER!!!!.
They are 1/8" NPT x -6AN male fittings

Well I figured you two would disagree on this also.

How about I just take my fittings with me to the speed shop and match them up then by the steel braided line to go with it.

Save your time, its a
1/8" NPT Male x -6AN.
I just hate when people throw around wrong information.
If you want I wont reply to any of your questions if you feel that way.

 

[65-440]

SSR is correct, they are 1/8 NPT into trans .......

 

[wedge5]

SSR that is not what I meant. Your info is always welcome. That was my sad attempt at making a joke about your beef with PoppaJ. My Bad.

CRT sells a kit with the lines and all the fittings. Not sure where you are in Il but he is just across the road in NW Indiana. I go past there every couple weeks.

i was looking at the kits but decided to go to local shop and build my own. now im wishing i would have just ordered the kit ! almost spent twice as much making my own !!

I see nothing wrong with mounting the cooler in the back. Street cars probably get plenty of rocks off of other cars and trucks and the front mounted coolers seem to hold up quite well. Sure, from time to time you get a hole or a broken windshield but it's usually not catastrophic plus you get rid of some weight off the front end. If you are worried about extra weight from the extra plumbing, use aluminum lines if they are available. The rear ac lines (aluminum) on my Durango run in a dangerous looking area but after 11 years, they look fine.

I agree, they are just convenient (you can't imagine how much trouble I have spelling that word). I ordered all my stuff through summit individually.
