I just bought a tranny from a 95 EX. Well I don't know how to tell whether or not I actually bought an EX tranny or a DX tranny. The number next to the serial number by the engine Id is S20. There is another number that says C5F P20. Is this any indication of what kind of tranny I bought? Or, do I just have to install it and see if I notice a difference? Any help would be greatly appreciated. I plan to swap the tranny this weekend, so the quicker the response the better.
