I just puchased a jdm h22 obd2 motor with trans from osaka. When it was delivered today it looked as if the trans was reciently been removed so I ran the numbers on it (m2a4) and it popped up as a 93-95 trans. The page I was looking at said it was geared slightly different then the m2y4 that was supposed to come with it. Is one trans better than the other besides one being newer? Should i send it back or try and get them to refund some money?
