Yesterday I was unfortunate enough to have my clutch give up while a few miles away from home. My clutch pedal started vibration a lot and then after a quick pop, I had no gears. I didn't know you could turn the engine off and select gear and then turn it back on in gear, as it was a first occurrence like that for me. I pushed the clutch in and with some extra force tried all gears, sometimes pumping the clutch, sometimes just holding it fully pressed on the pedal until I finally managed to get into 2nd gear. I didn't put crazy amount of weight on the gear lever but it definitely had some force to it. Once I turned the engine off, I tried all gears with no clutch pedal pressed and they all go in pretty smooth, 5th and 6th gear slightly harder than 1 trough 4 and reverse, but still go in and the gearstick doesn't pop out.
Could I have damaged something internal in the box itself by those forcible attempts to get into gear? 5th and 6th gear being a bit harder to engage with engine turned off makes me worry or is it normal for them to get in slightly harder than 1st and reverse for example? Anything I can try to check it? My mechanic will take the car next week as he's on holiday and I'm worried somewhat, but he said some bearing (throw-out?, input shaft?) went out most likely. What do you think?
The car is a diesel with a DMF, Alfa 147 C630 6-speed gearbox.
