HELP!!! 2006 Manual That Shakes/rattles/vibrates Upon Acceleration from a Stop!!!!!!
I own a 2006 Cobalt LS, coupe, 5 speed manual, with 75,000 miles. Recently I have been experiencing what I believe to be a transmission/clutch issue. I am a mature adult driver (no hot rodding), however I am the second owner of this vehicle. I am very competent mechanically and have owned many manual trans vehicles, including multiple GM 5 speeds. The following is the issue I am currently experiencing:
When accelerating from a complete stop, the car starts jerking/shaking from 1st to 2nd. I have noticed that it does more so when there is additional weight in the vehicle (i.e. 3 average size adults, rater than just the driver only).
When this happens the whole car shakes and rattles. It doesn't seem to matter what speed the clutch is released/feathered. I have also experimented with different shift patterns and RPM ranges, only minor changes if any? It feels as though the clutch is being 'dumped' in a low RPM, but just enough to keep the car from dying. From a bystander's view it looks as though the driver is first learning to drive.
I am not aware of any other mechanical issues. Also, just to note this doesn't occur when the car is accelerating from a rolling start. Only when there is the initial force to overcome. As I stated it is amplified by extra weight. I do not experience this in any other gears.
I have searched this forum and have not been able to locate a similar thread. Thank you in advanced for your help and I pray (literally) that this doesn't mean I need a new clutch or transmission.
