the trannys will line up and work on either blocks, the blocks are the same, only transmissions are different and which car they go in.....you can put a 92 b18a tranny on a 96b18b motor, it just has to go into a factory cable car like a 92-93 integra or a 90 crx etc..etc.........and you can do the opposite also, 92 motor with 95 tranny, just has to go into a hydraulic equipped car.....
