If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:


To start with check the automatic transmission fluid integrity. Make use of a dipstick to check the automatic transmission fluid level, while its running and while it’s in park. Keep in mind that the procedure to do so will vary greatly from manufacturer to manufacturer. You can definitely make use of the service manual present in your car’s dash.


Do a quick check for any debris or dirt in the fluid. Before proceeding further, you will need to make sure it is free of all this as a dirty ATF can adversely affect the operation of your transmission. If you discover any leaks and witness low fluid level then we recommend you to check for any signs of oil stains or puddles in your driveway.


Inspect your vehicle’s transmission control modules for any potential issues. Also check for any signs of water intrusion. Also look for any signs of corrosion on housings or connectors. If you do not find any issue with the above stated steps then consider monitoring your gear position and its functionality. While doing so you will be able to tell of the transmission is shifting or not by its drivability. In case it is floored and accelerated too slow then it is probably stuck a high gear - 4, 5, 6 or 7. In case it is accelerating too fast then it is stuck at a lower gear - 1, 2 or 3.
