I finally bought a 2g. 1998 GST. The transmission was grinding going into 2nd gear, so I took it to a transmission shop. I believe it is the synchs. Transmission shop said he needs to do a rebuild, but that parts are extremely hard to find. Tranny # is F5M30, but I am not seeing that anywhere. What kind of info or guidance could you possibly give me to help get this squared away?
