TD42 Gearbox Upgrade

[TomPlow]

Hey everyone I can feel my gearbox starting to go and just wondering if theirs anything out there that are better than the factory Nissan ones? Otherwise I would just be putting another TD42 gearbox back in.

These cogboxes are very strong mate. I think you'll find it hard to find a replacement that's as strong or better.
What exactly is happening to yours that you think it's about to die ?
