700r4 cooler

[muddawg]

i just put a new 700r4 in my k5, and im wondereing what kind of cooler is the best choice for my rig with a hot 454, 37's and 3/4 ton axles? How big does it need to be? Stacked plate or tube and fin? GVW rating?

stacked plate, big as possible. and do not think of not using the one through the rad as well

i dont have a radiator cooler, i have a griffin aluminum radiator. Will that make much of a difference?

What axle ratio? What stall on the converter?

I am using the 24000lb B&M cooler listed in the link above on my 700R4. It is a nice piece and is pretty compact and easy to install. I am very happy with it.

Be careful with that setup. Don't run the tranny in OD unless you are maintaining at least 1800 RPM's. Otherwise you will be adding alot of heat to the system.

tubed and finned. and use the largest one as possible. i run tow on my rig. after burning up a second tranny after only 80,000 miles i added another and run a 180 thermostat

Stacked plate coolers are more efficient then fin coolers are. They are tougher too.

B&M cooler

I just installed this last week on my 700R4 along with a smaller unit for my oil cooler and a 4 core radiator with dual 12" electric fans, my trans stays cool to the touch, and my temp gauge hasn't went over 200 degrees yet.

I am running 35's behind a 305/700R4 and I think it made a world of difference in shift smoothness, I used to have a sloppy shift into drive, now it is a firm shift but not too firm to bark the tires.

I bought my coolers from Jegs and my radiator from RadiatorBarn.com and the fans from Ebay ~ wired it all up myself.

Go big, but not too big where it can't heat to the proper temp to operate.

go with the biggest stacked plate one you can afford. They are superior to fin/tube units and way cheaper than a rebuild.
