clutch not disengaging seems likely
on the 2.4 there is a viewing hole, don't know if the 2.2 has it. can raise the car, have it running and visually tell if the clutch moves and is engaging/disengaging
also if the car is in the air, it should go into any gear even if the clutch won't disengage, as there won't really be much stress on the synchronizers with no ground to load against
