Just wondering if anyboby else has had trouble with gearbox noise. Started one morning when down-shifting in traffic. Thought it was a truck next to me. Went straight to the dealer and took a mechanic for a ride. He heard the noise but it wasn't as bad as earlier. I was told they would have to take the box out, but drive it for a couple of days easy til they could book it in. It also started to rattle when idling occasionally. When I took it in, they called me and said they could not hear anything so they didn't pull it out. Since then, I sometimes crunch the gears from 1st to 2nd. This may only happen twice a week. It has also developed another noise and vibration at about 3400rpm. Any ideas guys?
