bought a 6 spd yesterday and drove it 500 miles home from LA... enjoyed the drive but i noticed that the gearshift is constantly trembling/shaking with the engine. the most annoying part about it is that it makes a clicking noise which i think is the pleather boot rubbing against itself as the gearshift trembles. is this normal? if so, will the pleather break in and stop making this noise because it is REALLY aggravating.
