the WORST a stuck kick down switch will do is hold gears to the maximum shift point.
I was able to hold the gear all the way beyond the speed marks for the gear, and it still did not shift.

it's gotta be something in the valve body. motor sounded like it would explode... the tach is not working, so I do not know how high the RPM's got, but it was WAY beyond what the kick down switch would do.
