1990 honda accord auto trans problem????

I just bought a 90 accord ex and i think the trans computer might be bad. At
start up trans shifts into gear but slips a little. when you come to
complete stop the car wont move like the trans disengages, high rev but no
movement. If i shut the car off for at least 10 seconds it will shift into
gear again untill i come to a full stop again. I havent drained the fluid
yet for all i know it has the wrong fluid in it but the fact that shuting off
the key makes a difference leads me to an electrical problem. Hopefully
someone else has seen this problem before and can help me out.

Do a google search regarding blown capacitors in the ECU. It's age
related, so yours is the right age. Have you searched this NG? There
have been some posts even a few months ago. A drain-n-fill with Honda Z1
(or two or three) is just common sense, but it sounds like you might be
right about the electronics. There are a few caps and a resistor or two
that blow. It's a DIY job if you can solder. Some folks just go to the
wrecker and buy a used unit.

This may sound like a dumb question but is there an ECU and a trans computer
or are they both one and the same?

Mitsubishi/Honda ECM failures -- Fact or fiction:

The fact is, the Mitsubishi and Honda models of ECMs and TCUs
manufactured within the years of 1989-1994 utilize certain electrolytic
capacitors that after a certain number of hours or mileage, begin a
systematic breakdown. These capacitors eventually break their seal and
leak the electrolyte which is a corrosive substance. [SNIP]

You need a way to cycle the AT controller without shutting off the
engine, to truly assign the problem to the controller. Because in
shutting off the engine you are also letting the hydraulic pressure
fall to zero.

You could remove and reconnect its power connector/fuse with the engine
running, to see if that has the same effect.
