Hello, I'm Danny.

As a result of this issue is the check engine light on? There might be a transmission fault code stored in your vehicles computer as a result. First thing I would suggest is to check the automatic transmission fluid level. Here is a tutorial showing how to check the fluid level for an automatic transmission:

If the check engine light is on for your car to have a transmission fault code then I would suggest performing a CAN scan- Controller Area Network. This type of scan cover all systems in your car and can show any and all fault codes for your vehicle. Here is a tutorial showing how to perform a CAN scan:

After performing these tests get back to us with any information or fault codes and we can then properly diagnose any issues you are having on your vehicle. Hope this helps and thanks for using 2CarPros.
