auto tranmision dont shift between greas till i take foot off the gas

What is your question?

when it gets warm it comes out of greas but just reves up and wont go into the next one ( be it 2nd or 3rd untill I stop stepping on the gas and then it bangs into it. also seem to get worse as it gets hotter.

worse as it gets hotter
