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, it drives like a champ. I have just change the Solenoid, and I am thinking now it could be the TCU? please help me with thanks so much.

 

what was the code?

 

Thanks for your response, there is no code, or Engine Light on it. The D light will flash, turn off and turn back on its all good, and it is annoying the hell out of me.

 

Out of despreation I went to Mr. Transmission, and they told me that the problem is with the compute, and that will cost me about $770? Does it sound right? or is this something I can do for myself?

Thank you so much.

 

Can somebody help me with info please?????

 

You can see if you can obtain a TCU you know is in working condition then swap it in.

IIRC, the flashes actually have a pattern and that is your trans fault code. If it is indeed the computer, you can probably buy/install one for much less than $770.

 

Yes, I went to a local junk yard today, and found one for $50. After I install the TCU the light stopped flashing, but when Im about to stop in a red light it flashes quickly and the car will jerk a little bit, thats something new I discovered today, do you know what does it mean?

Thanks.

 

Both of my accords are stick so I don't know much about the TCU codes...

Maybe this can help
