It's only got 90,000 miles so I hope the transmission isn't toast. Thinking it may be an electronic problem or sensor. Do they have codes that can be scanned? No lights are on in the dash.

need more detail, does it have a hard time going from 1st gear to 2nd when cold, does it shift ok when hot? most common problem is you need to change the trans fluid and filter, not so costly to see if that solve the problem
