1993accordxx

Hello - I have a 1993 Accord that has been having issues with the 'D4' light flashing and the car not starting. It clears up if the car sits long enough and then drives fine for a little while, but it's been happening more often lately. I pulled the TCU codes and am getting the following:

1-Lock-up solenoid 'A' circuit open or shorted.
2-Lock-up solenoid 'B' circuit open or shorted.

7-Shift Solenoid 'A' circuit open or shorted.
8-Shift Solenoid 'B' circuit open or shorted.

14-Linear (line pressure control) solenoid open or shorted.

I am looking for any advice on how to fix these issues.

Thanks!

How do you pull the codes? If the TCU is faulty....then EBAY actually has some farely cheap. Just replaced mine, but I think the ECU might be faulty too.

I have a 92 accord with a transmission issue.
It won't let me shift out of park.
I use the shift lock release, start it in neutral.
It has major problems shifting from 1st to 2nd on its own. (manually it shifts between the two fine and once in 2nd it can get to 3rd on its own[for these reasons, I think it's electrical rather than mechanical])
I pulled TCM codes and it gave me a 3 and a 10 (three short flashes, long pause, one long flash, repeat).
All I can find out re: codes relates to ECU. If anyone can translate these for me or interpret these symptoms it would be GREATLY appreciated.

I just bought 93 Accord ex and showing symptoms of TCM issues. Where is the PXO # located so I can get the correct replacement?
It sometimes shifts very reluctantly from 2nd to 3rd and slips out of 4th on the freeway and wont re-engage until car is restarted. Then sometimes it behaves as nothing is wrong at all.
Help, please?
