The gearbox on my race car has developed a crunch when going from 3rd to 4th, I think the syncros are on the way out and need replacements, tried my local Honda Dealer but they would only sell the gearset (£800!!!) is there any one that does replacements for this box? I have searched without sucess Thanks!

 

Try Majestic Honda, you might find better pricing (assuming they ship to UK).
