#90 of 99 PLEASE HELP- 2006 manual jerking/shaking upon acceleration from stop!!!!!!!
Jun 17, 2013 (10:15 pm)
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 thank you in advanced for your help and I pray (literally) that this doesn't mean I need a new clutch or transmission.

Do replace the driver side speaker and that will fix that issue. On the other please read the rest of my posts so you know what to tell the tech when you take your Cobalt back to the service dept. This is a power train issue that should be covered under warranty up to 100k miles. I will also look back at post to find the correct verbage so you know. Do not pay anything for this is a GM problem that I discovered and they will not acknowledge. I will get back to you. Keep the faith!!! I had mine fixed over a year ago after much mcuh research!!

Please look at post 91. and also read my early post. I will get back with you as well.

The Torque Converter Clutch [TCC] "Lock-up" sequence can cause problems, to test if the TCC is the problem try this.
This is a power train issue and is covered under 100k warranty but GM will fix due to faulty issue. Do not pay for this fix. Keep smiling!!!!

Yes, I have read every post on here. But as far as I know there are no TCC on a manual trans. I may be wrong but can't find any resources that say it does.
Only post #36 come slight close to what I am experiencing. And I believe no one ever answered.

My tranny repair was covered under the 5y/100k power train warranty. If you have ongoing records with your dealership, they may still cover the valve replacement inside the tranny. My dealership worked on my tranny 3 times before they got it right.
