I almost forgot It's a 06 6sp with a 8.1 tcm ising it as a stand alone.Was working fine for awhile then just started to act like above.This setup has over 4000miles on it.

Thanks

Just thought I'd give a update on my 6sp standolne setup for my Allison
I have been trying to tune fore awhile had harsh 4>3 closed throttle downshift and inconsistent up shifts.I found a 6sp MD cal.I put a TCM in my setup WTH the MD cal.trans did the exact same shifting problems.Soo I decided to change out the Valvebody with a stock one I felt like I just won the lottery worked like a champ.Felt like a new Duramax.We took my VB apart and found that the shiftkit in syl.A the ball was not in the correct spot everything great now.now I can fine tune very little from were I'm at.
