Default 81 Corvette

I have an 81 Corvette I have let sit for along time and now the transmission doesn't want to change out of first gear. It is an automatic it changed out a few weeks ago now it doesn't want to work. It has plenty of fluid in it don't know what to do. Thanks for any suggestions

Pry the cover off the governor. Remove and clean the governor up. Weights and plunger probably sticking.

At what point are you measuring tranny fluid level? Engine and tranny need to be at operating temperature when you check.

An automatic not up-shifting? It's either the line or the modulator itself. Replace the rubber vacuum hose going to the modulator or if it's not that, it's the modulator itself. No Big deal. AND NOTHING ELSE. And possibly the line came off, period. No need to do a bunch of extra work. I have a twenty dollar bill that says it's the line.
