| Maybe someone has heard of my problem and can send me in the right direction. I recently (less than 1,100 miles ago) bought a 2007 Z06. Two days ago I heard a distinct transmission rattle in 1st gear after releasing the clutch. Took it to the dealer and was told this was normal and some transmissions do this and sometimes in different gears. Does this sound "normal" to anyone else? I will be discussing this with the regional service rep soon and would like any info I can get. Thanks.... | |

Replying to: billw501 (Apr 24, 2007 1:02 pm) made what many call the marbles in a can noise that many complained about over the years. Either mine has stopped doing it or I have just gotten used to it since I don't notice it any more, 64k miles. Problem is that since that is an old issue many at dealer will just blow off any noise when it could be a different issue, keep in pursuit to make sure. Randy

My vehicle has 8,600 miles on it. Two weeks ago the rear axle started making grinding/popping noises on the right side, after the car was park over night, once the car started moving forward the grinding noise starts to fade, when park over night the same noise returns. To check your car for these noises do the following. Back vehicle up at lease twenty feet turning steering wheel from left to right listen for the grinding or popping sounds, then drive car forward into a left or right turn remember this is only after the car has been park overnight so this is only for cold starts, if you hear what I have describe your positive traction is going bad. GM has two campaigns out regarding what should be done. First recommendation is to flush axle by changing rear end axle oil, second replace seals and clutches on positive traction. I also recommend to have ABS sensor check and part a describe as a “LINK” The services for the campaigns are free regardless of mileage.

Replying to: motorhead1 (Aug 07, 2007 6:17 am) Chevy has had posi noise for 40 years or more. First thing to try - take the car out and drive it in circles, left and right, or figure eights. This forces the plates in the posi to open up and let the grease in and get it all lubed up. A lot of posi noise can be cured this way. |

Replying to: motorhead1 (Aug 08, 2007 3:52 am) If you want, take it to the dealer. He will drain diff oil and replace it and the additive. They have TSB's telling them about this. If you are really mad and keep at them, they will replace the clutch pack for you. And the new one may be worse..... I'm not going to put my car into the hands of the dealer for such a small problem. You might also be hearing the front tires actually 'scrubbing' on the pavement in the tight turn. Those big tires do not like to be turned at such a sharp angle.

This is my first 6 speed auto trans in a vette and to tell you the truth I`m a little dissipointed. The shifts in paddle mode are very soft. I`ve tried to shift at different rpms to see if it would shift harder but it`s about the same all of the time. Is there something the dealer can do to make the shift more crisp of do I just have to live with it? Help
