Yeah? You're gonna need a new tune then.![]()
I'm with Hippie.
A well built 60 should do more then you need it to. Seems like more work than necessary. Although seeing you have already installed 2 toast 60's, I understand the want for change.



That would also mean changing driveshafts. Changing transfer case.
Unless the 4L60s are a 32 spline?
There's no reason a properly built/inspected 60 won't live up to your use. Not to mention that an improperly built/inspected 80 will do the same thing so that doesn't make much sense right now.
