Check my post under Electrical problems. The TCU's in Honda models 92-94 were made with faulty components. I only discovered this after doing extensive research. I have a 92 Honda accord and about a month ago I had the same problem as you. It was the Transmission Control Unit (TCU) that was bad and I replaced it myself (I am not a mechanic), so if I could do it, you could as well. In my post, I give detailed instructions on where it's location is and how to change it out with a new one. I hope you did not have the transmission rebuilt, because if the computer is bad, then having the transmission rebuilt will not fix the problem. The TCU is what communicates with your transmission so that they are in sync and will work properly together. I hope this helps you or anyone else who may be having this problem.

Needs to go to the transmission shop and rebuilt, or replace it with another.

And it needs to be diagnosed to be sure.
