79s, the 04 GMC 1500 4X4 had its tranny rebuilt at 111,000 miles, the transfer case was rebuilt a few months ago, the locker (G80) went out last year and I had to replace it, steering components were replaced with better Moogs and the powersteering is going tits up. The computer controlled push button autotrack 4wd is a pita. TCCM is shot, so that has to be replaced and re-flashed by the dealer. No other shops can flash the TCCM. I'm about ready to trade it in for an old dodge 12 valve cummins....
