Hello, I can help you with this! When doing a transmission service for this vehicle, you will set a (DTC) trouble code for a low pressure condition with transmission. This is a normal condition when replacing the filter and fluid. The first plan of action would be to clear the code. You would need I scan tool or code reader that is able to perform this function.I recommend that you have a professional technician from YourMechanic come to your location to clear this code and take a look at your check engine light. The body code is a separate issue that could be look at that time also.
