Strange....I only wind up in 6th gear when I PUT the transmission into 6th gear. LOL
I kid, I kid.....slush boxes have their uses too, I suppose. |

If you are trying to say it shifts into 6th to early, I think the people who have a vibration pretty much assumed that already. If you are not saying that, what the hell are you saying? Last edited by nyrfan; 08-07-2011 at 08:49 AM. |

Unfortunately, it seems like the auto tranny's goal in life is it get to 6th gear as fast as humanly (computer controlled) possible. I just leave mine in sport mode all the time. It shifts at redline when you go all out, but even during normal driving, at least it doesn't upshift at 1800 rpm.

Is the torque converter locking up too? Can you duplicate at other speeds since it is shifting early in auto mode? Can you replicate by matching rpms in other gears? Like I said earlier the manual cars do this too but at 2000 to 2200 rpms in third gear at about 30 to 35 mph. So while I hear what you are saying, I wonder if by you holding the shift to later isn't just a Bandaid and not the real fix for the real cause.

What octane are you guys using that are experiencing this? I have a manual and can cruise at 40MPH without a problem in 6th gear(I know the ratio's are different for the manual though). I use 93 octane and found that it did help with engine lugging when trying to accelerate from a low RPM(It would lug with 87, but not with 89 or higher).

Sterling, Since you have the manual transmission, try running at 30 to 35 mph in third gear when rpms are around 2000 and then hold steady speed. You should or may feel the engine almost feel like it is missing. If you are sitting still in neutral and barely bring it off idle and you may feel the same missing feeling in the engine. Let us know. I too can put the car into a lug situation 6th gear too early and it will pull clean, it's just one area that doesn't feel smooth that I can replicate in the two scenario's about. All you automatic guys, try to do the same thing off idle in park. If you can make it run rough sitting still, it isn't drive train it's engine tune.

Siper, cat back or headers and full exhaust? Cat back will change the timing of the exhaust waves and can make the poor exhaust manifold design even poorer since they do nothing to prevent reversion. I would like to figure out if this is a reversion issue or a engine tuning issue. You should be able to run an automatic in 6th gear and 1300 rpms with no vibration from the engine. All newer lockup converter auto's will jump to high gear and lock up the converter when there is little to no throttle input and will not cause it to do this. I don't think it is a transmission function issue, but rather a tune or reversion issue since the manual cars are doing it too although in a different situation.

My v6 2011 has the same issue. I was going to make an appointment to take it in for service. From reading all the posts, looks like theres no need.

Hmmm...I know other people have mentioned a "dead spot" in a certain rpm range. The new Vmax throttle body is supposed to take care of that. Not sure if it would help with the vibration issue.
I can't really say that I've noticed any weird vibrations at 45 mph. My rear view mirror will shake a little during a cold start, but after that it's smooth. I also usually run 93 gas, so not sure if that helps, too.
