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