Well it happened again Sunday. Everything was working good up until 3rd round of eliminations. Trans went from first to third again! HAd him covered by .040 at the start but couldn't catch him at the finish line! Car loses a tenth when I don't have second gear!

We have had the valve body out and checked the detent ball and spring. Everything looks good there. Installed a brand new shifter and cable, Air shifter plunger, striker block and dowel. We have tried air pressure from as low as 70PSI upto 140PSI and everywhere in between.

It's totally random when it does it. It may work 3 to 5 times in a row and then start acting up. Then it may start working again later in the day?

I am shutting off the air and going to finish the season shifting manually (I think I remember how)
