Having a hardtime finding a replacement tranny where I live at. So what other year accord is compadible with my 90 Accord Ex? I heard 94-97 will bolt on. But is there anything that I have to swap out of my tranny in order for it to work?

Also another question. My engine has 258k on it. I was thinking since I have to replace the tranny I was thinking about swapping it out for a H23 non-vtec cause its just for commuting. It's a direct bolt in right? My car is a obd1 and I can use my ECU for the H23 correct? Was thinking about going that route. Also what's the best place to order a H23 for a good price and reputible service. Thank you..
