    I've looked around and haven't been able to find a GM part number. I want the biggest, baddest, low pressure drop factory tranny cooler that GM makes, say off a 1 ton hauler truck. Any ideas?

    In about 96-97ish, G.M. was running a "Stacked-plate" design. looking at it, it had air-flow paths and fluid flow paths, that criss-crossed from one-plate to the next. The upper plates flowed one-way, the lower plates flowed in the oposite drction. (not like the cheeper versions, that stacked the same plates, one-top of other)
    That style cooler is by-far the best.
    Also, It takes up less-space (more air-flow into the radiator) and, it's not as restrictive as the other-stacked plate designs.(again, cleaner air flowing into the radiator).

    I would look at B&M, I'm pretty sure thier high-end coolers are the same style.

    I looked into GMs coolers they were way expensive. I did not see any diference between B&Ms coolers and the GM stock replacement for my cooler.
    I an running The <a target="_blank" href=http://www.bmracing.com/noflash/products/acc_tranCoolers.html> B&amp;M Super Coolers</a> for my Trans and Engine oil. They work very good.

    I have a factory oil cooler on my 90K5. It is exactly the same as the B&amp;M 28000 cooler installed for my transmission cooler.

    I forgot to also add that GMs coolers and the B&amp;M coolers are made by the same company. Both coolers have "Long Manufacturing" stamped on them. The B&amp;Ms are about $100 less. Than if you go and buy one from the dealer.
