Im currently looking for a tranny cooler on oregonperformancetransmission.com, they seem to have some real good prices but what would you guys recommend? they sell tru-cool and hayden, all different sizes, some say low pressure drop, etc. which size/brand would you guys prefer?

the 40K is a big one, expensive too. im not gonna tow anything and If I did it would only be a small motorcycle trailer or something like that. im lookin at the 18,000 gvw trucool one for around 50 bucks. Any better recommendations? my truck is a z71 with a factory hitch and tranny cooler, but the cooler looks tiny.

Interesting, I guess GM screwed me lol
Brandon, if you drill the plate to the size in the instructions you'll get harsh shifts as this kit was designed for F bodys and the trucks are different. I did a lot of research before installing my HD2 and most people liked this for a DD:
1-2: don't drill at all
2-3: use a .093 drill
3-4: use a .110 drill
I installed mine with those specs and it shifts a bit firmer (compared to stock) at partial throttle, but at WOT you get fast & firm shifts without banging, the best of both worlds IMO. I don't think you'll want firmer shifts for a DD honestly.
