My car has an automatic transmission.
Hi there. Check the shifter cable alignment to the transmission and make sure that the main valve is aligned up properly. The main valve could be off aligned causing the vehicle to not drive in the D and D3 selections. Also, check the harness to the transmission and make sure that all of the pins are working and making contact to the electrical system in the transmission. If you need further assistance with your transmission not shifting in the D and D3 selection, then seek out a professional, such as one from Your Mechanic, to help you.
