The tranny line you want to tap into is the top one. If you look at the back of your radiator, over next to the battery, you'll see what looks almost like a brake line going into the radiator tank. There's one at the top and one at the bottom on the driver's side of the car. You want to tap the top one and go from there.

Transmission cooler install

why does it matter which line you cut into? my mechanic tapped into the bottom...the fluid goes through the cooler which ever line you tap into to...if its that big a deal i could always go back and change it...but why does it matter?

 

[AverageJoe]

Because the aftermoarket cooler cools better than the stock cooler. So why should you use all that cooling power of the stock cooler to get the tranny temp down so much so it can be heated again by the radiator before it returns to the tranny?

Makes more sense to cool it a bit with the stock cooler, and then cool it really good by using the aftermarket.

See my point?

 

[CamellionCat]

ok so i tap the top one??????

what exactly do you mean by tap, cut it?????? where should i cut it on the bottom on the side on the top before it goes in the rad??????? so i just let the antifreeze go in the cooler or are both liquids suppost to go in the cooler?????

thanks for the help im really dumb for this type of sutff

i do see your point...but does the stock cooler really make it hotter? isnt its job also to cool?

 

[Rodeo Joe]

I would'nt say the stock cooler is making it hotter, but it's not cooling the fluid as much as it should. The top line on the 4R70W is the return line to the tranny. You want to use this one to tie into the cooler. I took off the top line from the radiator, put a nipple fitting into the radiator and ran a rubber tranny hose from there to the cooler....then another line from the cooler to the hard line that I unbolted. The hose slid right over it, no cutting involved.

Different models have different setups, it isn't always the top line, check it first.

As for mounting it, I made some brackets that go all the way across the front of the A/C condensor then the cooler mounts to those. That way nothing is held on by gay zip ties.

here's where i mounted mine. I kept the hot tranny cooler away from the ac condensor and the radiator.

Justin. I like your setup and if i keep the tbird the cooler will be first to go on her. How long did it take you and is that the way its supposed to be or did u mod it yourself.

 

[JustinH]

Its not very hard to mount it there, under the front splash guard, you will find that ford put a bracket there with predrilled holes. I just used the hardware that came with the tranny cooler, and bolted it right up. Also, I needed an additional lenth of cooler line, because it does not come with enough.

hey justin....

did you have to buy anything or did you just use the stuff that came with the cooler kit?????? i know that i cut the top line and just connect the tranny hose that came with the kit one side going to the rad and the other going to the transmission, but these people are talking about buying connectors and stuff.

The only thing you have to buy is about an extra 5ft of hose. Maybe some more hoseclamps. and a small pipe cutter if you don't have one. (Make sure its small, a big one is not needed nor will it fit) Now, if you got the kit i told you about, you should have gotten a plastic bag with a bunch of odds and ends in it. Assuming you have a '94-'97 mn12...
Look at the top fittings on the oem trans cooler. Unscrew the first fitting after the (top) hardline. Pull the hardline out. In the bag, find the barbed fitting that will screw directly into the same place as the fitting you just unscrewed. Attach a 11/32 (comes with kit, 3/8 hose will also work, the dimensions are very similar) hose to the barbed end, along with a hose clamp. Run that hose to the aux. cooler. Now get under the car slightly. You should be able to find both the feed and return lines. Make sure that you have a hold of the return line, and and about in the middle, cut it. Pull out the hardline you just cut, and attach another hose to the remaining line. Put two or three hose clamps on, just to make sure leaks are prevented, and run the remaining end to the cooler. Figure out a good place for it (justinh's place is a very good place). Check your trans fluid (refer to the the owners manual for the proper way) and fill it as need. You will need about a quart, maybe more. Im installing a new one for my new trans today (can't use the other one, gots crap in it!) and i plan on taking pictures and maybe writing a little article, the one currently on this site was very confusing to me, but maybe i'll make it worse.

ok...i guess my tranny cooler is tapped into my supply line right now...can i run another cooler tapped to my return line? double the cooling...

 

[94birdnj]

sry guys, don't mean to defer this post, but what's the best tranny cooler around now-a-days?......for a resonable price that is 50-100. plate style still in style? just had my tranny rebuilt and don't want to see it crap out for another 150k. heh

 

[WhiteBird101]

I've been recommending the b&m supercooler, 24000 gvwr, because it is the highest rating that you can get and still get a install kit. I think it was 50ish (from summitracing), and is plate style. Granted, any other cooler would work fine, but you might have to do some extensive part searching, then again, maybe not, but the b&m seems to be of high quality.

ok...i guess my tranny cooler is tapped into my supply line right now...can i run another cooler tapped to my return line? double the cooling...

Sure you could, but i think it would be kinda silly. If you really want one on the return line, just transfer it over, but you might be replacing a lot of hardline. Or do two. That works

 

[CamellionCat]

hey white bird i have one more question

if im going to be installing the cooler on the top line why am i going to have to refill the tranny fluid????????

Marvin M.

 

[AverageJoe]

Because by adding the cooler, you're adding volume to the tranny fluid system. It may be full now, but you've still got to fill the tranny cooler. So you won't have to like change or fluid or whatnot, just top it off and make sure its full. Ya know?
