What transmission cooler?

[Shibby50]

Well the Yank SS3600 and new built trans are sitting in the garage so it's time to add up the little things and get it all together.
Looking for a trans cooler. I see a few different brands like perma cool B&M supercoolers and hayden ones from most different f-body stores. Any input/experience on which ones are better than others?
Do most come with all the lines and fittings to put them right in?
I plan on running this one after the radiator cooler in-line with it. Is that the best way to do it?

And while I'm at it am I missing anything to do the install?

-SS3600 stall
-Built trans
-SFI flexplate
-ARP flexplate bolts
-ARP torque converter bolts
-Energy suspension trans bushing

How much fluid am I looking to use with a dry trans/stall/and cooler? And is it worth it to go with the Synthetic royal purple stuff or just ATF fluid. I know yank said to use synthetic with their stall but most people dont like to run it in their trans's. Sorry for all the quesitons. It's my first big trans install lol

braided stainless lines!
and the cooler of your choice, B&M is what I run, but I'm sure anything decent will work.

I'd run standard fluid, most trans builders will tell you NO syn. Capacity will depend on what cooler, lines and pan you run. I think they take around 12qts dry.

Are you talking about replacing All the trans lines? Or just what comes with the cooler? And if so do they make a kit to do it?

Yea, talking about replacing the entire run as its also a good idea to take the lines OUT of the radiator and run them exclusively thru the external cooler.

 

[Shibby50]

So it's better to run it as a separate cooler and not in-line them?

 

[Eagle]

Yep, thats what I was told and that's how I run mine. I also put a small fan on my cooler, which is tied in with the main fans and triggers high/low speeds just like the stock fans do.

 

[Shibby50]

Thanks, I planned on doing the fan thing even though some people said it was overkill. I'd rather be on the safe side of things.

Ot but what size fittings are on the stock trans going to the hard lines that connect to the cooler?

 

[Shibby50]

Well from what I can find on tec. I think I'm going to follow what this guy did. Except plug the radiator holes and run the lines straight to the cooler with a fan.

But I think I'm only going to run -6 lines

Yank says do NOT use synthetic in their converters. I used the standard BM cooler that's popular on tech and got it from speed Inc. Installed the cooler with all the supplied fittings and haven't had a problem in two years so far. My trans is stock though. I'm sure with your setup the braided stuff might be worth it.

-6 is what you want to use. Jegs sells kits ready to go, specific to trans type and includes the fittings. Might want to look into that.

I used the b&m 70264 iirc. Comes with everything you need. I ran mine inline though. Trans to rad cooler to b&m cooler back to the trans. I believe that I what yank recommended to me. I have to do a standalone cooler now, but it worked well to inline it.

 

[CrunkMaro]

the reason its ran inline stock is so the trans temps can get up to operating temp via coolant temps. its a good system.
eagle's car is a heavily modified car. he probably doesn't have to worry about getting to operating temps with that converter and that much PAH in there.


if you run standalone run a trans temp gauge so you don't beat on your trans when its cold. cold trans (vs operating temp and not overheating temp) is not good. just because its built doesn't mean its unaffected by trans fluid temperature.

I went with one like this

It was the biggest one I could find. I think it was made for a diesel truck or something. I had to cut stuff to make it fit, it was no big deal.

I went from the rad to the cooler back to the trans. I figured this was the most efficient way of cooling the trans. I thought because the rad coolant temp could get to about 180 degrees going through the rad first then through the cooler would cool better.
