Re: 92 accord overdrive problem
I had a 92 accord that did the same thing, the car would down shift into 3rd and the d4 light would come on steady when malfunctioning. Mine was definitely the TCU. Replaced it and didn't have a problem with it from that point forward.
Hope this helps.
BTW do not buy the TCU from Honda, It will cost you approx. 550 from them.

Wouldn't you check the codes first and see what they might be telling you before you just replace the TCU.
It would be funny to replace the TCU and get the same code because a solenoid was bad......my two cents.
