engine trouble: unable to shift to any gear

hi.

i was supposed to jet off to school but as i tried to go on first gear on my px i noticed that the engine didn't lurch forward. i let go of the clutch while it was on first but it was as if the engine was on neutral. i tried 2nd, 3rd, 4th, but nothing, the engine won't engage any of the gears. clutch and gear cables seem to be intact, plus i seem to hear this weird whirring sound on the engine side. has someone else experienced this? what could be the first thing that's wrong with my px.

 thanks, thanks.

Maybe you need to change your clutch plates/lining. Baka manipis na yung cork lining kaya dumudulas na. Nangyari na sa akin yan, ganyan din ang symptoms. Good as new ulit nung nagpalit ako ng clutch plates. Have it checked. Your mechanic knows what to do.

correct!
