What up HT! Got some issues with my civic, some help would be awesome! Alright, I have a D16Y7 in my 99 Civic Sedan that has been swapped from a 96 Civic Hatch(same motor the Sedan had). My tranny has been acting weird the D4 Light is blinking(which I know indicates that something is wrong with the tranny) but I just had the tranny replaced because it was in limp mode. Now the tranny shifts fine and smooth but only problem is that the D4 Light still blinks, when the gear is put in D4 it is boggy while trying to drive and the Automatic gear has to be manually shifted into 2, then 3 and then 4. Is it the PCM/ECU? Or is it a different problem?
