Are there any ways to differentiate between different transmissions with the same name? I have a '89 crx si with a dohc zc swap and am unsure of what transmission it has. I know its an L3 but i dont know if it is from the si or the integra the motor came from. Is there any way of telling without completely taking it apart? More importantly, and the reason im asking, is that my left cv boot is torn and the guy tried to replace the axle, but said he couldnt find an axle that would fit(said he even tried one for an 89 crx si). Should it matter what the transmission is if they are both L3s or does the different gear ratios and final drive of the different transmissions matter for which axle is used?
