Lessons learned? Rely on no one but yourself. Beware of Turks bearing gifts: they may say ‘yes, we can fix it’ to every problem posed but this is not always the case. We have now spent £££s on this transmission issue (I no longer call it a gear-box issue as there was nothing ever wrong with the gear box) and have wasted over a week at anchor waiting for various mechanics and boat yards to fix this problem. Still, you live and learn, innit?
