Well mines not solved either. First two trips down the track tonite. It would make the shift. Messed with the tune and got it to make the shift twice. But on the way home in wouldnt do it on a 1st gear downshift, but from a roll twice on the highway it did.

I hit limiter on 2 to 3 the other day. I have rpm built 4l80.I had things set to shift at 6500 and 7000 limilter. I will maybe lower shift rpm don't really want to raise limiter.
I may have to lower my mph also. Hopefully nothing is wrong with trans.

Just lower the shift point til it shifts. They take a lot of time to shift, we had mine at 6200 in time to shift before 6900 on the 2-3 and 6400 on the 1-2. good luck.
