Which puts it out of a DIY repair viability
I have rebuilt a nissan bluebird gearbox, through lack of availability. At the moment a 1.2 panda or 500 isn't that hard to come by, I paid £60 for one a couple of years ago
People have put insane amount of torque through these gearboxes,on the dragstrip much more than a ford cosworth, without any problems, most issues are caused by low oil over heating the bearing cage causing it to collapse, driven well and maintained they have been known to last 1/2 million miles, I had two that have done 1/4 million
