    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.

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

    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.
