92 accord check engine light d4 flashing

This is a typical Honda problem. unfourtunatly their design on the transmissions are not the best. Most of the times when you have a flashing light on the shifter on a honda it is the beginning of an internal transmission problem, not a major one but most likley one of the solonoids in it. just for future reference to you make sure to keep your trans fluid changed on the recommend mileage because they do have an internal filter that is extremley common for plugging up and giving a no shift condition. Hope this helps. swiftautorepairs.com
