Honda Repair: 1992 Honda Accord Ex, transmission control unit, honda accord ex

Question
My D4 light intermittently flashes and the transmission started to slip when the light does flash.  What could cause this to happen?

Answer
Does it feel like it's stuck in second gear and won't shift? If so it is most definitely the TCM or transmission control unit. It is located next to the ECU on the passenger floor. I have seen many problems with these units and have replaced them for numerous problems. Hope this helps! If you have any more questions please feel free to contact me!
