Google is smart. Noise, vibration, and harshness. Yep, mine is a bit of all of that but I assumed it was the Voodoo doing it's thing. It is not and never has been a smooth shifting gear box. A little chunky between 1-2-3-4. Not nearly as bad 4-5-6. None of which to the level to call it an issue to warrant taking it in to have it looked at so I'm going with no.
My shifter knob now turns about 1/10 of a turn to a dead stop either way from center. It's the knob, not the shifter lever.
Car is smooth as silk. Rides great. Shifter fantastic. Can believe how tight this car is,
especially after reading these forums. I expected it to buzz like an '84 IROC with 137k and wander like one on bias plies. Amazing!
