My car has an automatic transmission.

Hello and thank you for contacting Your Mechanic. The drive light (D light) is coming on from the transmission range sensor. The sensor on the transmission tells the computer what gear the transmission is currently in. When the sensor fails, the D light will flash or an engine light will come on with a code. I recommend replacing the transmission range sensor. If you need assistance with troubleshooting your wiring, then seek out a professional, preferably a professional from YourMechanic to help you with your electrical issue.
