Hi there, I have a 1994 Honda Accord, and recently my D light started to flash from no where. I thought at first it could be my Speed Sensor, that is not the case. This is whats doing, I will start the Engine Specially in the morning and the D light will flush, and when I'm about to take of it will have a rough shift, and travels around 20-30 mph. Sometimes I will pull over and shut off the engine, and turn on back the D light is gone, and it drives like a champ after that.

I have just change the Solenoid, and I am thinking now it could be the TCU, which I did today, it stopped flashing, and drives fine, but when Im about to stop in a red light suddenly the D light will blink and disappear just like that, and this is something new I discovered today.

What could be please somebody help me with this. Thanks.

 

Tell us how you specially start the motor in the morning?

 

Ok this is what happened, and this is how the D light started to blink. One day my car won't start at all for no reason. I tried it several times, and finally it did and along the way the D light started to blink, since then I had a night mare with this car. If it is transmission I would have fix it and get over, and I am sure it is not transmission, there is no a reason to change a new tranny and it is all over the same problem.
