TF727 will not up shift to 2nd on launch

First run at the track was a normal run. Then, with a normal launch, when I shifted to second, it did not change. I got out of it and shifted again and it went to 3rd. Three runs with the same results.
I have a B&M ratchet shifter and a Turbo action Cheeta XtremeAction manual valve body.
Just driving around the pit area the Trans shifts normally. I went to run with a moderate launch to see if that had something to do with it but was rained out before getting to run.

Any idea of what went wrong?

Thanks
