maybe for the trannies? I know they got a bad reputation from that era. I have a '96 3/4 8800 gvwr that has hauled a lot more than it is rated for. I had reverse go out, I pulled the transmission and had it rebuilt, then I reinstalled it. Less than a year later it went out again, trans shop would not warranty it so I tried my hand at rebuilding and that was about 6 years ago. I guess I have been lucky. Mostly had front end problems, and the rearend went out a couple years ago. If I had to to do over again, I would have put 4.10's in instead of the 3.54, I just didn't feel like doing the front at the same time.
