sounds like a possible transmission problem. is there any warning lights on. may also be a cat converter. those sometimes feel like a trans mission. have it looked at right away and let me know what you find out

Thank you for your help. I took it in and they told me that it was a transmission problem. I thought that it might be, but the way it was fine and then it just would not go over 20. was a shock. This was just hard right around christmas for me. It was alot $2000.00 to fix. I hoped that it was only something simple. I just did not want to get ripped off getting it fixed. But I tried and called around. Thank you for your help.
