I have a 2006 lancer Es 5 speed. Yesterday I noticed in first and second gear it vibrates bad and I lose a little power. 3,4,5 gear are ok. Does anyone know what this could be?

 

what vibrates? the shifter, or the whole car? make sure your e-brake isn't seized on, and it's just fighting a stall...clutch could be slipping, power loss in a manual transmission is normally a slipping clutch, cause the gears sure aren't slipping.

 

The whole car shakes

 

so it's only in those gears, and is doesn't matter what speed or RPM? is your tranny making any other noises? I feel like your input shaft bearing might be shot.
