1979 Porshce 928 Help
I am 17 and I am having problems with the transmision on my 1979 Porsche 928. When i start the car in neutral or any other gear, it works fine. But when I still am not moving yet and try to shift into ANY gear including reverse, I get a grinding noise. My clutch pedal is in all the way. What would be causing this. If i push the stick really fast into the gear it shifts, but if i do it at a normal speed, I hear a grinding and I immediatly stop the shift. After I start moving on the road (actually driving) it shifts fine. Does anybody have any insight or where I can get any. Also, where can I get a diagram of the transmission?? Thanks...
