1992 Honda Accord 4 cyl Two Wheel Drive Automatic 161k miles

I have been to one national transmission company to attempt to figure out why my tranny won't shift. The light stays on green in drive no matter what gear it is in.
This first company told me they were going to do an electrical diagnosis. Whether they did or not I wasn't to know until quite sometime later. After about forty minutes the gentlrman came in and said it was my TCM and he could order me one for the next day at the cost of $360.00. So I agreed then he requested a deposit of $100.00 dollars. Which I did. Come the next day I drove the car back to have the tcm installed. It took all of 15 minutes before he came back and said it wasn't the tcm and I would need a new tranny at a cost of $1800.00 to $2000.00 I asked for my deposit back as he wouldn't let me see the so called new one and he refused. Well so much for that lesson.
I then took it to a family owned business and told them what this guy did and they told me they get alot of thier customers.
So Ron actually did an electrical diagnosis at a discount. I learned it takes about an hour to do one right. Well he was able to get it to shift with the original tcm but then it shorted out again. I learned that the tcm has to be programed and matched to the tranny, you can't just pull one off of a junker and use it. I am still waiting to hear back from him as he told me it might be a week before he could get one. Oh, I forgot to say that the first guy returned my car with no radio and my muffler was rattling quite severly. I am sorry for rambling on.

My question is can you tell me what the TCM looks like or perhaps provide a picture? And where is it located on the car? Don't worry about everything else I guess I was mostly venting.

I would really appreciate it if you could answer those two questions.
Kind Regards,
Burndoc

Hi there,

Thank you for the donation,

See pic 1 for the location and Pic 2 is a general indication of what a control ECU looks like, they are all much the same in design.

*Snip*
Sir:
Did you get this resolved yet? I had almost exactly the same symptoms in my '92 automatic. The D3 or D4 light was on in every drive range; the car wanted to start out in 3rd gear all of the time. Would never shift down into lower gears, except manually. I think it would never shift into 4th either, I forget. Anyways, I had gotten water in behind the dash and it ran down and shorted out some components in the TCM module, which is located right under the carpet under the front passesnger's feet. I could see the component parts that were burnt in my module. The local junkyard wanted $100.00 for a second hand one. I plugged it in, puit it back together and my car ran great, exactly like it was supposed to.
