this sort of shows what was happening. maybe i wasn't hitting the kickdown when i floored it at about 30 mph because it downshifted then upshifted at 4k rpm. when i floored it from 50 mph, it downshifted then raced towards redline , i didn't wait to see when it upshifted but it was at around 5k rpm. that's the only scenario that makes sense because otherwise it appears that it should have shifted at the same rpm/speed if i was hitting the kickdown switch....
