Sticking in 2nd gear under heavy accel.

I posted this by mistake in the 12v forum. Sorry.

The truck has started its newest trick, won't shift out of 2nd under heavy acceleration, like merging onto the highway. Shifts fine if I'm driving it easy or just normally. I have to let off the fuel and let it wind down for a second, then it will shift to third hard.

It seems to have started this after I manually downshifted to 1st last weekend when towing. Made a sort of emergency stop, and I shifted to 1st at about 30 mph, which I don't normally do. Any ideas?

The problem got a lot worse the next day, and I ended up replacing the gov. pressure and trans. speed sensors. That cured it.

Thanks to Tim at TRE for the advice, you da man!
