Re: Transmission Noise on Gt"s
yeah, mine gets a slight rattle under load. Most noticed in 4th on mine. I understand this is common. I discussed it with my dealer service department - they said it was the standard gear knob and that the optional one would deaden the rattle. I have never heard such a load in my life (what better way to try and get you on the options, even after you have bought the car!!)
I now just rev it harder and let that gorgeous sound from the rear block out any rattle.
Enjoy, and welcome to the club.
