M6 Getting Hard to Shift
So I took the car out for a drive tonight, and about thirty minutes in it started to get fairly hard to shift into gear. I came to a stop, pushing the clutch all the way in, and still had quite a bit of difficulty shifting from neutral to first. Pulling into my carport soon afterwards, I stopped and attempted to shift into reverse, and it entirely refused to go in, no matter what I tried. Also, when I shifted into the other gears the transmission made a clicking noise sometimes, and also hummed/buzzed abnormally (I could be imagining that one though).
I've only had the car a bit more than a week, but it shifted fairly smoothly previously. I was doing a bit of spirited driving, but nothing too crazy, so I don't think it could be that. Any ideas on what it could be? Master/slave cylinder? Clutch? Shifter? Help would be greatly appreciated.
