Question: I am currently rebuilding a B18a1 Motor for my brothers 92 Integra - OBD1. We have been looking for a B18a1 automatic transmission for the longest time and cannot find one. I am able to find B18b1 automatic transmissions all day long though. My question is, will an automatic B18b1 Transmission work with a B18a1 motor? If so, what parts will be needed to swap this over? Thanks!
