I have a 92 Honda accord Automatic lx, the d4 light started off blinking then stopped, now it stays on continuously. Causing rpm's to rev higher than normal. Does not feel as if it is shifting properly, Started off intermittent now is constant, able to drive by shifting gears manually. If driven in D4 at start up pedal can be pushed to the floor, an the car accelerates at a very slow speed, very slow pick up. Could this be a solenoid ? or the belts in the transmission? very unsure as to what it could be. No code can be pulled.

Videos that might help you.

This light is indicating a fault in the automatic gear box, it can be excessive slippage (you may feel nothing unusual) or other problems. you must have it scanned by a dealer or ****** repair shop to find out what is causing the light to come on.

check transmission fluid level- run/drive for about 10 min. , park car- check with engine running- add fluid if needed- ,if fluid NOT low- transmission filter needs to be changed

That is a fault indication for your transmission. I am not positive but I think that indicates a fault in your forth gear solenoid. Your transmission is not going to last very long driving it like that. When you stomp on the gas and it does not accelerate, your clutch discs are slipping and burning. It won't take much of that to ruin them. You may want to take it to a good Honda transmission place. I don't know about the older Hondas, but the newer ones don't have any provision for removing a pan and working on them. They don't even have a line replacable filter.
Check your transmission fluid dipstick. If its not a nice "bright" red color, you are probably burning up your clutches. The darker the fluid, the more contaminated it is.

i have a 92' honda accord lx, it has a problem of the D4 light flashing and the car wouldnt start, but i could wait a few minutes and try again and it would start.

transmision computer needs to be flashed or replaced.

you have a transmission fault the D4 light blinks to tell you that there is a transmission problem when the light is blinking the transmission computer put the transmission into limp home mode so it will not shift normally and you should try not to drive it very far when it gets to this stage you need to have the transmission codes check to pin point the problem

Chris, I believe u have 2 problems. The flashing D4 light indicates a transmission problem, which Honda recommends having checked out right away. It wouldn't hurt to change the fluid, there is no filter on the 92 accord. I suspect the problem is more than changing the fluid though. The other problem is only starting in Neutral. This may be a faulty neutral safety switch. It's located at the base of the shift selector, and covered by the console. Let me know if u need directions on how to remove/install it. Good luck.

d4 is flashing as a trouble code for the automatic transmission... i would say without research that it is a code for a transmission solenoid. maybe while washing the car some water got in and caused a short...these solenoids are usually weatherproof....you could try disconnscting the battery for 30 secs..to clear the trouble code and then start the car. remember you may lose your preset info!

Blinking light means there is a trouble code.There is a procedure to manually pull codes from the computer.Have the codes checked,have them written down.It could be just shift solenoids,or could even be something more serious,but thats the starting point.
