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.

Arch now u know the years and the miles cant you tell me any info now.
It's important to know the all the information as tomousecap's repy proved.
On certain years there are problems with certain things and having all the information helps us to provide accurate answers.
For instance, now that I know you have a 2003 I know that it came with Dexron III transmission fluid and not Transynd. That means you should have changed your transmission fluid at the very minimum of twice over the past years along with the spin-on filter.
In any case it looks like the ABS symptom ties in with the problem you have and hopefully your issue will be solved.
