Is a 4L80E Auto- tranny compatable with a 4L60E? I want to put it in a 1997Chevy S-10, 2.2. - Answered by a verified Chevy Mechanic
Jul 18, 2013 · The 6L80e is a brute of a transmission and a great advancement over the 4L60e which we all know is a slushbox when you put power to it. The 6L80e's have been know to handle 600 to the wheels, some report putting down more. This is out of a factory built trans, no bells or whistles.
