Default TH400 2,3 shift not occuring

I got a 85 fox ls1 th400 swap that I finally got together and took it to the track last Friday.
The car 1,2 shift is occuring at 4,200 rpms, I think the govenor just needs re-weighted to fix that.
However the 2,3 shift never occured, so the last 300 feet I was bouncing off the rev-limiter. Was wondering what could be wrong with it not doing the 2,3 shift, and what to look at.
Thank you
