So I have an 06 coupe and noticed that when im driving and going around 38-40 mph the car will stutter and shake when accelerating slowly. I noticed that this only happens when the rpms are at around 1800. Happens more often when going up hill.

Is this normal? I believe this is when the car is switching from 3rd to 4th gear. Doesnt happen when accelerating at normal speed.

Any suggestions?
car only has 40k

 

Do a search I believe this has been discuss, and I believe that there is a TSB on this issue. Hopefully this helps you.

 

Not sure on this one. Could be a torque converter issue. If there is a tsb maybe it is a re-flash for the tranny software?

 

Call the dealership and ask. You are under warranty still.

 

I had this same issue and they replace the trans computer and all is good I believe it is a TSB. Good luck. Kirk

 

Thanks for y'alls help! Took it to the dealer with the TSB and they went ahead and replaced the valve body control on the transmission that was causing the issue.
