Yeah I got a new gearbox on eBay and when I took the engine out I opened it up and found a little piece of metro that came of the shaft where it meets the selector drum, it started with the popping out of second, then the shaft must have broke as a result :/ or mybe something else, there was two pieces of metal the same so I'm guessing it isn't the first time it's happened. That's the main reason I decided just to fit the new engine, incase it's going to be a recurring problem
