Thread necro, but did this ever happen? I have an 8.1L based engine and ZF6 to add to my son's GMT400.

I nominate you to be the first.

I don't mind. We're yanking the interior on the C3500 soon, so I can cut and weld up the new transmission tunnel. I am also trying to find someone to refresh the trans, since it has 180K miles on it. Sad, most shops are like " I have too much automatic work to mess with manuals these days".

Not only that, they do so many more autos that they're not gonna be as efficient with something unfamiliar and won't make as much off a job like this. I'd just run it first, it could be butter. Especially being a 2wd, yanking it back out down the road is no biggie.
