yeah, you just answered it yourself. Your stock tranny is a D and the new (CRV) donor is a B, IR the two won't mate up! You need a B series FWD tranny, preferably hydro, since that it what you currently have. If your cheap, HASport has a Hydro to Cable converter, but you will do better with the CRV or a GSR tranny from any year CRV or 94+ GSR. And to the person who said the CRV is a 4WD....WRONG...more CRV's are FWD, only a few are 4WD.
