I have a 99 silverado automatic transmission when I put it into drive and get going right around 20-30 MPH it wont stay in gear but if I put it into 2nd it stays just fine and my transmission fluid is a little over full. If that's not the problem what could you help me?

If I Rev the rpms high enough it will catch and keep going. But I'm worried about doing that can it harm the tranny more by doing so? Thanks for this site :-)

Sounds like its slipping-Check the transmission fluid level and condition if okay-bring it in and have it further checked out by a tranny shop.
