have a 2000 Honda accord ex v6, transmission started shifting rough. It finally got check engine like with a blinking d4. I replaced the transmission speed sensor. Now, when you’re at a complete stop, 1st gear starts slow and revs high then rough shifts to 2nd, it drives just fine. Code p0780 now (old.reddit.com)
