Over drive is usually the gear to go first,you may check the over drive sensor,but most of the time this is a sign of tranny going bad.
If you want a quick fix, won't fix forever but it may help for a month or two. Run sea foams tranny "fix it" fluid threw it. But if it's not even trying and just slipping right away I'd be looking for a good rebuild soon
