I know exacly why its doing that. Something has broken.





Sorry, That doesn't help much does it.

If it is a clutch problem it will tend to be doing one of three things.
1) It will either not diss-engage at all when you push the pedal and you will not be able to get it into gear with the engine running, or if it's in gear and driving it, it will stall when you stop.
2) The clutch will drag and only partially diss-engage and it will crunch the gears when you change, especially reverse.
3) the clutch will slip or not engage properly resulting in the engine free revving as if you had your foot on the clutch pedal when you try to accelerate hard.

Sounds to me like you have either an issue with your gearbox probably a bearing collapsed, or you have an engine mount collapsed and the gear selector linkage is jammed. Its difficult to give a more definative answer without looking at the car but reading what you have said I very much doubt if its the clutch.
