Interesting. You wont know till you get it back on the road I guess. Curious how the 4L80 will do and if it wants to hunt for lock up/overdrive at certain rpm's. You could always swap the rear ratio if need be. What axle do you run? An axle with a 3rd member could be like a poor man's quick change if you had another
3rd member with a different ratio to swap in for testing, if it hunts a lot. Nothing more aggravating than that constant fear change. I hate my 2015 trans for that reason, and also the v4 mode.
