The quality of gear change on my 82 Porsche 924 is poor. What are possible causes?

It does not slot into second as fluidly and smoothly as it should, and I feel a slight grating (no sound but a vibration through my hand) when changing up to third. No problems with downshifts. The car has done 75 000 miles and has not had gearbox oil or clutch changed ever. Clutch does not slip. Are there simple, cheap fixes that I could try, before contemplating a big gearbox repair?

Your problem is in the transmission! The solution is to take it to a Porsche dealership for transmission service. A simple, cheap fix you might try is to change the oil in the transmission.

Is there a leak from the box? Have it checked.



As a last resort if it is filled, change it to a Mobil Synthetic Hypoid oil for manual tranny's. Works like magic in a 915 tranny
