Gearbox noise and vibration can be heard and felt the shift linkage under
some circumstances.  One is if you replace the shifter bushings with
delrin.  When putting some pressure on the linkage the hard delrin will
transmit what sounds like your teeth on a grinding stone, especially in 3rd
gear. This is mitigated by lubricating with some heavy duty grease, but
does not go away completely.
