Hello, this morning I was driving and i noticed that the 'D' symbol was no longer showing on the dash. What could be going on? When I got to my destination, I turned my car off and then back on and still not working?

This is one of two things. First it could be the shifter itself that has an internal issue that is not illuminating the D any longer. However, the other likely cause is the shifter has lost connection with the cluster or the cluster has an internal fault on the circuit board. The way this works is the cluster gets a signal from the transmission sensor to tell it what gear it is in. Then the cluster tells the shifter what to illuminate. Basically we need to monitor the voltage on the blue wire at the shifter to confirm what the issue is.
