Allison Tran
I have erratic shifting with my 8.1 Allison 1000 tran. 50mph and above my tack shows 2200 to 2500 up and down from my tran shifting. Any one else every had this problem with this Allison 1000 tran.

I just service it and it still does it. I keep it between 60 and 70 and it does it more then. I will put some miles on it this week end since I service it I done a road test of 10 or so miles and it was still doing it. will report on it after I put some miles on it this week end.
