I have been through quite a few of these post to try to find the problem with my 92 honda. The D4 light starting staying on several months ago. I would reset with either unhooking battery or by taking out the ECU fuse. It eventually would not reset and all the searching I did basically led me to the TCM. I took mine out and did have burnt stuff. I had these fixed and still same thing. I then just went and bought a remaned TCM. The D4 light continues to stay on. I have checked for the click in both of the transmission solenoids and they seemed to be ok. I don't know what to check now???? I have to put the key in the key slot to get it out of park now. Any ideas? Thanks for any help

The D4 light of the 92 Civic is NOT a diagnostic warning light as it is for 96-00 Civics. It's just a light.

Could be a bad shift position console switch or a short in the D4 light circuit.

But start here:

Please clarify what is happening.

Is the d4 staying on while other lights are on, or is the d4 the only one ever on

In other words If you are in park are the P and d4 lights on or is the d4 the only one on regardless of gear selection?

D4 light stays on in any gear. Seem to only have D2 and D3.

Are you saying the P, R, and N lights don't work?

Is the problem only the cluster lights or only the shifter lights or both?

Do you now understand that the D4 light of your Civic is not used to indicate transmission malfunctions?
