jomichael - i am not familiar with the t-5 or the corvette trannies, but in a 4x4 truck i would want something beefier. i had a 92 chevy with the NV-4500 5 speed, and I loved the hell out of it. It has a compund low as well as a great OD gear. My truck cruised at 70 at just over 2000rpm, just purring along. This tranny was pretty widely used in chevy trucks, and you shouldn't have too much problem finding one if you choose to use it. I drove that truck for about 40,000 miles and never even had to look at it, and now my sister drives it, the truck has 170,000 miles on it a new motor but still the factory tranny. That thing is tough as nails and would be my recomendation.
