V6 vibrations at low rpm's (30-40 mph)

If I lift my foot or if I accelerate the vibration goes away temporarly. Now if you put the car in "M" (Manual Mode) then depress one of the shifter buttons on the steering wheel to have the car enter paddle shift. You can avoid the vibration all togather because who in the correct mind would be in 6th gear while driving at 37 mph. I really think Chevrolet should do something about that shift point. Perhaps keep it in 5th gear until say 50 mph or X rpm.

thank you +1 that is what i am saying

Went for a run without a helmet, an 05 Mustang decided it didn't like me.

You would think with near 1500 posts in 60 days, it would be easier to understand. LOL

I CANT SPELL I CANT TYPE ALL I CAN DO IS BE A POST WHORE and i am damn good at it

how did you guys not understand? lol and that does make sense. I put the car in 6th at about 50mph, 45 way to low and the bogging down does make sense.

Personally, I've never noticed any vibration.

Everyone else who has been complaining about the V6 A6 vibration at 45 mph, well I think I have found the problem.

Last night while I was driving to work, I had it in D because I wanted to cruise to work when I noticed the vibration again from 43 to 45 MPH... so i did an experiment.

I shifted from D to M because i had a sneaky suspicion... since I drive so much in M, I hit the down shift button and BOOM I was driving in 6th gear doing 45 MPH.... weird.

Now when i drive in M, i normally dont even touch 6th gear until i am at least doing 50-55 MPH. On average, I cruise 45 to 55 MPH in 5th gear or so.

------- I edited to here and gave up...taking too much time. (except for the spelling mistakes that were underlined v v v)

i was right in D mode when the computer controls the shifting it shifts WAY to early into 6th and it causes heavy vibration so much so your rear view mirror rattles like a bass hit

my only guess for this problem is one of two things A it is programed to save you as much fuel as possible IE get to 6th as fast as possible i notice when your just cruising it shifts about 1,800 or below rpm as me in M i shift perfectly at 2,000 on ave or close to it

or B the computer coding is screwed up and it feels it needs to shift into 6th so damn early either way the computer should be recoded to shift at a higher speed then 45 it knocks it too low on the RPM and bogs to the point the car vibrates

my only way around this and the main reason i started to drive in M was to avoid this i knew something was wrong i never guessed it was the computer shifting time programing ugh

anyhoo anyone else try this i got all shift points down from 1est to 6th IE 10mph shift to 2ed and so forth everyone else try this tell me what you think

and Jeff hi if your reading this can you call your tech people asking them about changing the coding for the shift points? with out voiding anything to improve a more stable non vibrating ride? is it possible?

thank you for your time Nightfall (i learn ever car i own to the T and all its flaws)

Good job investigating and playing around with the car, seriously. I had read what some V6 owners were saying about the A6 and the low speed issues. I thought it sounded like what my car will do cruising into our neighborhood. I do 30mph or less, that's right between 1st and 2nd and it will "shudder" like what's been described.

As for your grammar. The title of this thread, "...problum", is why I checked it out. I did mention this to you in another thread but nobody else said a word. I didn't want to get dinged for mentioning it a second time. I will reiterate, you are a very open and honest person.

i stand by what i stated its the codeing my biggest guess is its trying to save you gas and thus trying to climb though the gears too fast boging down the car

why i asked Jeff into this call his GM tech people speak to them reguarding this matter

I hate this problem, even going up a hill the car will go in 6th and just start shaking looking for power. I always feel like the car is just constantly shifting in and out of 6th everywhere i go at any speed.

Why are you guys driving 45 mph anyway??

You have to get to 90 some how lol, No its more of a RPM range of where the problem occurs

Good info, bad grammer
