    It appears that they really don't care about fixing this vibration defect. At first they could have publish a real fix and then proceed to correct this vibration defect after the first production year (2015) but instead they continued to produce this this garbage for 2016 and 2017. Profit rules them.

    And this is exactly why all the food executives lost their bonuses this year due to recalls and warranty claim handling.

    It can take a year to implement a solution if you know what the problem is...

    There has to be separate studies done on all the components to narrow down what is at highest risk. Once found, if it is a internally controlled part; you have to design, and validate a solution, which means running another vehicle or set of vheicles through durability. Oh there also has a business case.

    They could be piggy backing the fix to 2018 validation to keep cost lower, or due to resource availability.

    Last I heard the route cause was center support bearings.

    As I first posted mine didn't have this problem ..I have 5200 miles on mine now and it had the vibe from 45 and up .. Last night I installed my drag tires and headed to the track ... I had just had them balanced because they had turned on the rims from hard launches .. To my surprise it had zero Vibes at any speed ..So I'm going to have the same shop that did the balance on my drag tires rebalance my stock tires and see what happens ..

    In case anyone on this thread wants to shim down their transmission crossmember- the stock bolt is an M12 1.75mm pitch with about 1.5" of threads. I was just under my car monkeying with this, and with .25" of shims, it is cutting it very tight (i.e. the stock bolt doesn't have many turns on it.) I'm going to swap the stock bolts with something longer this week.

    edit - went to Lowe's last night and they had M12 1.75 in 60mm length in stock. $2.50 per pack of 2 bolts. Worked like a champ for over .25" of shim. Might be a little long for anyone doing less than .25" of shim. Lowes also sells a 50mm length M12, which might work better for less shim. DSCN2249.JPG

    I'd be interested to know the info on the bolts you source if you can post that info for us.

    Just an FYI too:
    Kelly @BMR has come up with a longer bolt + shim kit for the trans mount adjustment. I think his info about this is in the suspension tech sub-forum.

    Can you post up your source for your last statement regarding center support bearing being the issue?

    I had plenty of thread left after adding 1/4 shims, maybe the automatic x member is different!

    I also get that clunk and it's bad. Now I am also getting it shifting from gear to gear until I am in 4th gear. 5th and 6th no clunk. It's embarrassing to have a new car that sounds like the bottom is falling out with 8000 miles on it. Mine goes in on Thursday and I have a feeling it's going to be lime talking to a 16 year old kid about it as the Ford dealers here in Orlando seem clueless about Mustangs. Going to a different dealer this time but not expecting much difference

    Reference my posts here where I included images of my Service Center invoices - and tell your Service Manager to contact the Ford Engineering team, they are well aware of this "warranty" problem.

    One more thing:
    The MOST IMPORTANT FACTOR OF YOUR CONCERN is to tell your Service Writer you WANT to take a Tech OR Shop Foreman on a test drive. YOU drive the car some distance first and point out your concerns exactly when they occur. Do NOT take some Dealer 5-minute scripted trip around the dealership block or into local neighborhoods!! Take the test drive out to the HIGHWAY or major roads where you can get it up to speed and stop/start to demonstrate the issues. You cannot demonstrate such problems with the common Dealership scripted pre-mapped routes. Then let the Tech drive the vehicle back - when you are in the passenger seat, STILL CONTINUE to point out when the vehicle is acting up.

    I can't stress it enough to take a Tech OR the Shop Foreman on a LENGTHY test drive to point out the concerns.

    My one test drive alone was nearly 30 mins so that I could really demo how the car was driving/reacting at certain speeds on different road surfaces and the intrusiveness of the driveline vibe.

    If you do not get the satisfaction from your Dealer then you must open up a claim with a Ford Customer Service Regional Rep in your area so you can get the concern elevated - at which point your Ford Service Center MUST work with that CSR and get the Ford Engineering Team involved. If you still can't get satisfaction, hit Fords Social Media, give totally negative reviews to ANY Ford Customer Satisfaction Survey that you receive in email AND contact the BBB.

    Don't give up!

    Thanks for the great advice Cobra Jet. I will print off your info tomorrow and take it with me for reference. I was already telling myself that I needed to take the tech out for a test ride as I notice it's at its worst between 60 to 65 MPH.
    I absolutely will not be taking that they can't see anything wrong as for an answer.

    I just got done trying some more shim (went from .25 to about .385) which did not make any difference for my vibe with they dynotech 1-pc DS. The M12 1.75 pitch 60mm bolts from lowes worked just fine, but would probably be too long for less than .25" of shims.)

    The last time I tried the hose clamp trick, I could not get that last little bit of vibration better. Today I tried taping (yes, tape - the high strength ductwork foil tape) two small washers at various spots corresponding to the 4 available bolt holes. Once I found the best combination, I bolted the washers into their proper holes. On stands, there's still just a tiny hint of noise at 60mph, but on the street it feels smooth now.

    What's really amazing is just how sensitive the driveline is to even the smallest amount of imbalance. You wouldn't think a tiny washer less than a gram would make any dang difference, but it makes all the difference in the world. BTW, I filmed the underside of the car with a GoPro running through the gears on jack stands, and you can't see or hear the vibration. Crazy how much gets transmitted to the body of the car.

    Does anyone know what the yellow corner on the 6r80 yoke lines up with. The yellow dot on my driveshaft will have to be on right or left of yellow dot.

    Same here, as "widespread" as this issue is , I have not seen any video evidence of the vibration . It would be interesting to see at what magnitude various people are seeing .
