shift nob is Sticky
 

My shift knob is skicking in gear over 2000 RPM, it has to be yanked out. It also does not want to shift into 3th, 4th, or 5th, however if I pump the clutch a couple of times it goes into gear ok.

The Mechanic said I need a new clutch, but I thought that clutches last the life of a car. my car has 100K mile it. Any help would be great.

You'll have to check whether its a hydrolic or mechanical clutch and whether it is self adjusting or not. Clutches wont last the life of the car. it all depends on the driver. a clutch works with friction plates that allow some give untill the cluch engages. once those plates are gone however..... time for a new cluch. it could just be needing adjustment.
