  1. First thing you will need to do is pull the check engine light codes. (Autozone does it for FREE).

    Post the codes back here in the comments below and we will assist you further.

  2. If the transmission fluid is low it will shift hard and out of the normal shifting pattern. While you are at it also check your engine oil level. As mentioned by the techs, have your Auto Zone scan your engine light codes.
