Output speed sensor, most likely. It tells the computer AND the
speedometer how fast the vehicle's moving, and this info is relied upon to
shift the gears. Get it in to a competent transmission diagnostician (not
the dealer, and not Scaamco) NOW. The longer you drive the vehicle in
"limp home" (permanent 2nd gear) mode, the more damage you'll do.
