Mazda5 gearbox issues.. Please Help...
 

Hey guys im new here an need of some help if possible.
I have a 2010 Mazda5 2.0 Furano (mk1) Petrol.
It has a 6 speed manual gearbox but 6th gear is completely busted. (All other gears are fine).
my only option is get a used gearbox an swap them over. But im struggling to find one
Does anyone know if the Mazda 3 shares the same gearbox as i know they share various other parts.
Or my other option is to find a Ford Duratec gearbox thats the same but again i dont know what model has the 6 speed that will fit.......
Any Help or advice can give will be greatly appreciated
