What does it mean when the D on the gear shift of 2004 Honda elements flashes?

When the "D" on the gear shift of a 2004 Honda Element flashes, it typically indicates a transmission issue or malfunction. This could signal that the vehicle is in " limp mode," meaning it will limit functionality to protect the transmission from further damage. It's advisable to check for any diagnostic trouble codes using an OBD-II scanner and consult a mechanic for further inspection and repair.
