Hi Russell

Sorry to hear about the gearbox. As a fellow Mk3 turbo owner, what power and torque were you running? I'm on a BBR stage 2 - so 300 bhp but not sure what torque...

2010 on Gearboxes are stronger.

Thanks for that any reason why they are stronger?? What are the differences??
Many thanks Russell

The problem always is no-one takes them apart and reports back what broke, if they did and it's a recurring theme then it's possible a stronger part could be made for it.

In the early boxes it’s the 3rd gear synchro that fails. But the bearings can also wear on the 4thgearshaft.

Other issue is a broken selector fork

Thanks for the replies casing is OK so all new gears and bearings complete new innards a recon gearbox £500 this is only costing £750 so hopefully will handle the power, no problem ;-)

Did you find out what actually broke?
