I kept getting the run around here in Cairns with mechanics telling me to get another box and put it in but this seem like it counter productive as it's a clean box and I lost these gears while driving with no noise clunks or bumps, it's just like it's in neutral when I put it into 3rd or 4th. Im thinking it's the forks or spline that the forks move that are worn off because of the additional power of the turbo but not sure and I see this can be replaced to an aftermarket full spline part that is much stronger. Any thoughts?
