If that's the case, then she could have shifted the car herself. There's only one gear change...I mean how hard is that? I drove a powerglide equipped dragster too and have shifted it more than once myself when a air line would blow or it ran out of CO2. It was right between my legs, the shifter.
I also noticed that also(her red lght), didn't want to pile on the negativity. She must have red lighted because she left right after the car and caught the car way too early.
Got to sit in those cars for hours and envision the run at the shop by yourself. Use the controls with your eyes closed. Go over and over the run in your mind and know when the car is supposed to shift. Must get to be one with the car before you get to the track, because your not in the car for long at the track. Not much time to learn there where you could put other people in danger.
She wasn't holding onto one of these where you have to shift the car yourself and everything else. No electronics to shift the car. And I shift the car the first time at .9 seconds after I leave the line at 100mph.
