Hello,
I have a 92 honda accord ex wagon. My symptoms are as follows:
-occasionally, the car will not start and I see the d4 light blinking rapidly; if I wait for about 10 minutes, the car will start normally
-sometimes, the car will start but the d4 light steadily blinks slowly. In this case, I can drive the car but the car runs very sluggishly.

My mechanic retrieved the following codes: 1-2-7-8 corresponding the number of blinks.

I have since then replaced my old 28100-PX0-A21 with a rebuilt 28100-PX0-A22 tcm which I paid $200 for. I did this because I noticed that some capacitors were starting to leak. According to my local Honda dealer, this model A22 supersedes the A21 model. I thought this solved my problem but last night the same thing happened again!

Obviously there is something else wrong. Any help will be appreciated.

maybe that is the wrong tcm, did you check the electrical connectons on the tranny, grounds etc..

what are those codes for anyway??

the codes are for the shift and lockup solenoids. i had problems with the shift one too and i canged it. no problems since.

Is it expensive to replace these shift and lockup solenoids?

If not, is it advisable just to change them all of them?
