D4 blinking 1995 honda accord
This is involved. When the D4 light blinks, it is indicating a problem with the input or output systems for the A/T. If you find your Service Check Connector (it should be near or at the top of the kick panel on the passenger's side; it's usually blue and has two holes in it; it is at the end of a wire so don't look for a fixed unit; it is often simply tucked in behind the top of the kick panel. You should pull the kick panel out to find it) you can insert a paper clip so that it connects the two holes. Then, if you turn your ignition to ON II (do not start the car) the D4 light will blink out a code, using both long and short blinks. The blinks have to be carefully counted. Problem codes 1 through 9 care indicated by short blinks. Problem codes 10 through 15 are indicated by a series of long and short blinks (you have to add them together to get the code).
I tell you all this to indicate that the procedure is fairly involved, and since you probably don't have a list of what the codes mean, I would have to say that it would be best to find, if you can, a Honda dealer to read the codes and check your transmission. Most of these problems are connector or sensor related and are usually indicated by the transmission not shifting from one gear to another, or by the transmission jerking hard when it shifts. If your having no problems and you are in a position to not have access to a Honda service department, you can find the backup radio fuse in your engine compartment fuse box and take it out(not with the car running) for 10 seconds or so, then put it back. It will clear the computer. If the D4 starts blinking again, it would indicate that the warning was not just a glitch.
I really hope that this is helpful; I'm sorry if it is only disheartening.
