I have a question about my 1999 Honda Accord EX V6. When I turn the key to turn the car on and all the lights on the instrument panel light up, the D4 and the Park gauges light up and then the D4 turns off and the Park stays lit up. Is that normal?

 

Yeah, I think it's like a bulb-check. The tranny controller uses the D4 lamp kinda like a "CHECK-ENGINE" light for trans problems and it's doing it's own self-check for a couple seconds when you first turn on the key.
