new transmission question

Great information, everyone. LockDoc that link is packed full of good stuff. I admit I get impatient with the "must wait 60 seconds" rule on the search page. It makes my brain hurt.
Looks like most of you all are running 700r4, I'd still like to hear more from those with 2004r, especially since they were never put in trucks. I'm not hauling gravel or anything, but it's still a truck and who knows what will end up in the bed down the road.
All the overdrives have deeper firsts than the th350c that's in there now. Is the 3.08 a bad rear end because of the RPMs in 4th? I checked some online calculators and they looked fine.
