For the benefit of an old fart, how are those Allison's holding up? I'm a moderator on loan from a sister site, so I know very little about the Chebby's. Other than what a tech friend of mine tells me. What do you want to know about a Cummins? LOL I'm a Mopar guy. I've left a few of you guys behind over the years. (There goes my ego again LOL)

Come to think of it, I don't think I've ever seen the GM version. Plenty of Fords, and even they are a gray area for me. But I am one Hello a mechanic and Engineer. I can help with techniques. Lots of Old school tips and tricks.
