It means that the transmission solenoid sensor is out.There are two of them that are located close to the dip stick for checking your fluid. Take it out and order a new part from Honda. that should help. then reset your computer by disconecting the negative battery cable.
i guess the same as blinking d light on honda element that just started today on an 06 element. has to go to fix it shop and ill let you know what it is soon. never had this happen on older hondas?
Maybe the hood isn't shut tight?

Honda Element was created in 2003.
Transmission error
Maybe a loose wire
This is an indication you have a bulb burnt out on the side the blinker is blinking real fast.
