I've been seeing several posts regarding the 6-speed grinding problem. Mine doesn't have an audible grind, but almost always between 2nd and 3rd, and sometimes from 3rd to 4th, I can feel the gears meshing through the stick. I noticed that the faster the engine is running, the smoother the shift. Should I feel the gears when I shift? Have any TSB's been issued regarding the transmission? Are there certain manufacturing dates that the problem 6-speeds come from? Thanks.
