...at the one mounted in front of the truck. I am getting ready to mount a 7.3 psd intercooler swap and am looking at replacing the factory transmission cooler at the divers side front. This was a factory option way back for people with the A518. I already have a auxiliary cooler with the fan at the rear of the truck under the bed, but would still like better atf cooling. With all the work involved in an intercooler swap, I figured this would be a good time to upgrade. trouble is, it is hard to find a cooler with 1/2 lines going in and out. Anyone already beat me to this mod? Let me know what you found, please.

 

I'm there now.

I've been thinking of one like this . . . http://www.summitracing.com/parts/PRM-1005/ but the lines are too small at 11/64". They also have similar models running AN6 fittings. We want AN8 (1/2").

The idea is to mount it above the AC condensing coil.

 

David,is the under bed cooler not doing it's job or you are looking for more cooling? I am going to put under bed in mine when I start putting it back together. I want to take a look at yours when I get a chance and get some ideas on mounting. Oh yea! How the heck are ya?? haven't seen you in almost a year. In case you didn't know the chapter 18 is trying to put a drag race together sometime in oct. or november. Keep an eye on the chapter 18 news at bottom of the forums. Gotta go to Chapel QUEER and see in-laws...Later

 

bigragu, forgive us for drifting.

Hey Alan,
Nah, I'm trying to keep with the Stock/OEM cooling scheme . . . . sorta.

If one runs the stock/OEM AC condenser in its stock/OEM location on the IC, then that leaves me a 3 or 4 inch slot across the top of the IC. And only a 3/4" to 1" gap to put it.



Alan, I'd enjoy a local diesel get together. Let's say I'm getting ready for it.

 

I have yet to hear a difinitive on this, but aren't the fittings for the cooler lines on the tranny necked up to 1/2" from 3/8"? If this is true, would it matter if the lines and cooler were a smaller diameter? When I had my auto out for my rc project, I thought the tapped holes in the tranny were the same size as my old 727 from 1975.

 

I know for a fact that B&M performance products carries one(sorry, no link, but I do have the part number and will post later on on this tread). It is 21" x 10" x 1" thick, if I recall, and it has (4) 1/2" lines coming out of one side. It is a combined atf and engine oil auxiliary cooler, the tube and fin type. pricey, though at around $130.00. I know hayden doesn't carry one...had the local parts guy look it up. I should check w/ deraleproducts.com. They make one for our trucks w/ the 10" fan on it.
I already have the one w/ the fan on it, a B&M one, 1/2" lines, w/ Tstat set for 180 degrees. I live how it works, it does it's job...problem is, it doesn't take my tuck long to hit 180-188 degrees. A couple of stops waiting for the light to turn green after (generally after 30 minutes of driving after start up and coming on to in town traffic) gets the fan goin'. Not that I am complaining about the auxiliary cooler (one of my better investments to my truck), I would like it to take a little longer, say an hour or so, before the ATF temps hit 180, is all.

 

This is what I came up with . . ..

 

Where did you find the atf cooler? Also, check your PM's

 

Bump for bigragu. What did you come up with?

My factory transmission cooler is currently deleted right now due to lack of room from the PSD IC install. The line just loops back to the trans, for the moment.

 

TH, what I finally did was this, let me back up a little.
I 1st had to set goals, and the 1st goal was not to spend unneccesary cash on a atf cooler that was probably inferior to the stocker or equal. After searching all manufacturers and researching sizes(length, width, and thickness) I couldn't find one to fit behind the front grill next to the huge psd IC, and hardly anyone manufacture's atf coolers made with 1/2" in/out piping for the 1st gens. So after carefully playing around with the stock atf cooler, finding the "best" spot for reusing(when I say best, I mean adequate airflow for cooling, close as possible to the tranny, and also to avoid damage from twigs, rocks, etc.)I ended up mounting it on the drivers side, just under the door, close to the frame, but outside of the frame. You will see structure under there that curves up as the structure heads towards the front of the truck. The flange on this structure is around 1 3/4" wide, which was wide enough to attach the cooler onto with screws. I removed the fancy bracketry that was attached originally to the cooler that dodge used to make it work at the front of the truck. I reused the stock cooler piping that rolled backwards; in fact, I pointed the piping towards the drivers side door(explained better, I installed the cooler upside down with the piping rolling towards the drivers side door), and was able to catch my 1/2" atf hoses that are running from the atf to the B&M auxiliary cooler and fan mounted under the bed.(same location the dealer would mount an auxiliary cooler if you wanted that option back in the 90's) I planned the atf to route this way:
From the tranny the atf gets cooled at the water/oil cooler 1st that is under the turbo, from there heads to the B&M cooler fan 2nd, then now hits the newly relocated stock cooler that came from the front of the truck 3rd, then lastly goes through an atf filter mounted under the hood next to the battery 4th, then back to the tranny. In all, if you count the atf filter and its housing, I still maintained 4 areas of atf cooling. My temps went back to normal like I had it before I swapped in the psd intercooler, which is 180 degrees max.
Being a sheetmetal worker, I was able to measure and fabricate a 16 gage housing that protects the atf cooler from rocks, twigs, but still picks up good air flow that passes under the truck while driving. I feel that the airflow is better down there than where Chrysler placed it originally in the front. Just my opinion.
Look really close in that location. This structure I am talking about is not the frame, but structure next to it, between the frame and the body sheetmetal.

 

i think i found one, its a derale... im heading to the parts store now to see what the guy came up with :-D
