I've got notchy shifting and clunking on one car, and silky smooth with no clunking on the other.
Are both the same year/totally stock shifter? I've heard conflicting reports- some say later year MT82's are better and then there are others saying they're just as bad. I get both the clunk and the notchy 2nd on my 2011 but it's bearable. This is my first stick shift and I assumed it was fairly normal.
