Evening all, first post and not someone who has a great knowledge or maintaining cars, so please dumb down for a beginner!!
I've had my 2009 1.6l manual i30 for about 3 years. It's only done 40k miles, but I've had recurring issues with the gear changes for a while. First time, they started getting difficult regularly, as in I had to force it into gear. I got a new clutch installed and that seemed to solve it for a few months.
However, today I noticed that it was slightly tougher than before, wasn't too worried as I thought that would be normal once the clutch had worn in. Unfortunately, there were several times when I couldn't get it into gear at all, certainly lower gears. I thought it was me, that I wasn't depressing the clutch all the way, but it was difficult occasionally when I made sure I did. It's only lower gears, mostly when it's cold but not exclusively. It's occasional, most of the time it's completely smooth, sometimes it's rough and a handful of times it won't go in at all. I also seemed to notice an occasional clunk as it went down into first gear, though not sure if that's a normal occurrence, never hear it before.
Is my gearbox on the way out or is there something simpler I can check? I've checked the clutch fluid and that's within the right filling level.
Thank you
