3rd gear crunch on a 56 reg MX5 with 20k miles?
Aug 06 2011
I've had my 6-speed MX-5 (56 reg, 20k miles) for a year now, and have noticed that when driven abit more enthusiastically, the 3rd gear occasionally 'crunches' or 'grinds' when put in. Would also like to say this is after the engine has warmed up too.
This happens even with the clutch fully pressed down, so it isn't that. My car has always been taken care of, and drove quite gently I would say, and just had it's 4th year service in May. But it obviously doesn't do alot of miles as you can see.
Is it possible that the synchromesh on the 3rd gear has worn already?? Or would a gearbox oil change help matters?
Any advice would be much appreciated...
