is this a problem that can be repaired externally by checking and possibly replacing the wiring? Are the codes an internal problem with the transmission. It shifts fine when I drive the car. I just want to rectify that check engine light.
If it shifts fine the problem may be intermittent so you can bring the vehicle to your local parts store and have them use a scantool to erase the codes and see if they come back....If they do you will need to have parts tested/replaced and its internal to the transmission but not too big of a job, a few hours.
