What are the codes for transmission related problems?
First, check for transmission related trouble codes in the computer. You may find any of the following codes: P0700, P0715, P0720, P0731, P0732, P0733, or P0734. You can read any of these codes with an inexpensive code reader. But you’ll need a scan tool with some live data capabilities to continue the diagnosis.
