Hi and thanks for using 2CarPros.

If the check engine light is on, the first thing you need to have done is scan the computer for trouble codes. That will guide us to what is causing the problem. Many things can cause it.

First, here is a video that shows how to check for trouble codes:

Sounds like it is most likely a transmission issue, does the speedometer work?
read this guide on transmission issues, it will help

Take care,
Joe

Does the speedometer work I think is the response Joe was looking for. It sounds like it could be the turbine speed sensor. Here is the location so you can check it out. Please run the codes as well.
