I just bought an 02 Silverado HD 4x4. Duramax, Allison, and some type of New process T-Case. [any idea of the new process I.D. number?]
From what I've read in the manual, and the Net, if You ordered bucket seat's, it would then come with a manual shifted T-case, mine has the split 40/60 bench, so it's a pushbutton {remember the old Chrysler push button transmission's?] I hope this work's better that those did. /forums/images/graemlins/rotfl.gif
It doe's have that Massive American Gear and Axle 11 1/2" rear axle however, and as luck would have it, a comparison between it and the Dana 80 just came out in Fourwheeler Mag. It is one hell of an axle!! /forums/images/graemlins/cool.gif
