Default How much trans cooler is needed

I'm running the setup in my signature and am wondering how mych trans cooler is needed. Stock 4L60e with Fuddle 3200 stall, am thinking about using this cooler http://store.summitracing.com/partde...&view=1&N=700+ without running fluid through the trans. I have room to run two of them if needed.

For a single cooler and bypassing the radiator that is bit small imo. Im currently bypassing the radiator and am using the b&m 70266. With your stall i would say either get a bigger cooler or run two.

When it comes to trans coolers, my motto has always been:
go big or go home
Looks like you have a nice little hot rod, now see if you can get that 4L60E to live for a while. The cooler the fluid the better unless you live in Alaska.
Give this one a look: http://www.jegs.com/i/B&M/130/70274/10002/-1
If you have room for two, it'll be easier to plumb one big one.

Change your trans fluid often, your tranny will love you for it. Will make it last a while longer. If you can get a shift kit installed for a reasonable price, they will also help your performance and longevity.
(you can wait until you rebuild it to do the shift kit, the sooner the better.)

I suggest using AN fittings and braided hose too. You don't ever want a hose or clamp failure causing you to oil down the track. Spend a little more up front and be much happier down the road with the peace of mind.
Get a good trans temp gauge while you're at it so you can keep a close eye on your tranny temps. Worth their weight in gold. IMHO
Good luck.

Cool beans.
Hope you go with the AN fittings on the install. Just did mine and it looks so much more professional. Hey, if you haven't already done so, you might consider a B&M or TCI deep finned aluminum trans pan as well. They help cool because of the extra fluid and the aluminum heat transfer. Good luck.

Good idea on the finned pan. Yes AN fittings also. I bid on a used (new in box) on the other day but had slip on fittings but didn't notice. Luckily I didn't break reserve so he can keep it.

Sounds like you're on the right track.
One word of caution for yoo on the alum trans pans:
drain plug gaskets they come with are the thick nylon ones, and I have personally seen several people keep tightening them over and over until they strip the threads out. Dummy who chose those gaskets to go with the pans should be shot. Anyway, just use RTV silicone sealer on it, or get a 1/2" thin copper gasket from your parts store and thow that thick nylon gasket in the trash before it gets you in trouble.
Good luck.

I ordered this one http://www.jegs.com/i/JEGS/555/60345/10002/-1 along with their push loc hose and fittings. I'm moving it to the back though. I was running two coolers before one with a fan but this should do the trick.

Nice!
There is no such thing as too big when it comes to trans coolers. I have two of those on my 4WD K5 Blazer. Room wasn't a problem, mounted them under the winch bumper and fabbed up a rock guard for them. Extreme? Yeah, but when you go hill climbing in the sand dunes @ 115*F . . . you can't get too much cooling.

Where in back of the car are you mounting that one Mr. DopeFedZ?
