Credit should be given to jimmyb08SD as it is his idea. And he is trying compile information to see if there is a pattern for this problem on like trucks, or is it happening to trucks that are different (eg. 6.5' vs 5.5' beds, SuperCrew vs SuperCab, one piece drive shaft vs two piece drive shaft).The information that we can all provide may help us come up with a solution.The mounted camera is a great idea that may help Ford diagnose the problem and then come up the resolution.

 

1. 2011 Screw 6.5 bed, 4x4, 3.5 EB, 3.73 rear, Ca., present all takeoffs in low gear, empty or loaded
2. 2011 Super Crew 6.5' bed, 4x4, 3.5L EcoBoost, 3.55LS, 5800 miles, shudder present @ 3-5 mph in 1st gear only, empty. Never seen salt. Built March 23, 2011.,
3. 2011 Super Crew 6.5" bed, 4x4, 5.0 V8, 3.73 LS, 5500 miles, shudder present @ 3-5 mph. Built November 2010.

As a side note, I bought Firestone Ride-Rite Air bags and compressor... once the bags are installed I will run them up with air to stiffen the rear susp. and see if the shudder is still present. I am of the belief the shudder is from the 2 pc drive shaft, but this is a way to eliminate or confirm the axle wrap theory as the bags will hold the leafs in place.

 

Here we go, some early similarities =

Lets keep it going.

 

Found this on another forum.

Ford just came out with this today!


2011 F-150 WITH THE 3.5L OR 5.0L ENGINE AND 6R80 TRANSMISSION BUILT ON OR BETWEEN 2/1/2011 TO 4/1/2011 SHUDDER DURING 2-1 DOWNSHIFT 5-7MPH (8-11KPH)
SOME APPLICATIONS OF THE 2011 F-150 VEHICLES WITH THE 3.5L OR 5.0L ENGINE BUILT ON OR BETWEEN 02/1/2011 UNTIL 4/1/2011 MAY EXHIBIT A SHUDDER DURING A 2-1 COASTING DOWNSHIFT TYPICALLY FOUND AT SPEEDS OF 5-7 MPH (8-11KPH). USE IDS TO MONITOR FOLLOWING PIDS, IN_GEAR MODE,GEAR_RAT, VSS TO VERIFY IT IS THE 2-1 DOWNSHIFT. IF THE SHUDDER IS ONLY PRESENT ON THE 2-1 COASTING DOWNSHIFT REPLACE THE C-CLUTCH (INTERMEDIATE) FRICTION PLATES FOLLOWING WSM SECTION 307-01 AND USE AVAILABLE SERVICE LABOR TIME STANDARD OPERATIONS. IF THE SHUDDER OCCURS AT ANY OTHER VEHICLE SPEED OR GEAR CHANGE EVENT DISREGUARD THIS PROCEDURE AND FOLLOW NORMAL WSM SECTION 307-01 DIAGNOSIS BY SYMPTOM FOR FURTHER DIAGNOSTICS

 

Here is another.

Heres Another TSB on Ecoboost engines also just came out today.

SOME 2011 F-150 VEHICLES EQUIPPED WITH A 3.5L ECOBOOST ENGINE MAY EXHIBIT AN INTERMITTENT MIL LIGHT WITH MISCELLANEOUS HEATED OXYGEN SENSOR BANK 1 OR TRANSMISSION DTCS, A LACK OF POWER COMPLAINT, OR SHIFT QUALITY ISSUES. INSPECT THE ENGINE HARNESS TAKEOUT FOR THE BANK 1 UEGO FOR A CHAFE CAUSED BY THE TRANSMISSION CASTING. IF WIRING CHAFE IS NOTED ON THE ENGINE HARNESS, REPAIR THE HARNESS AS PER ONLINE WIRING DIAGRAM (EVTM) SECTION 5 PAGES 5-8 AND WRAP THE HARNESS WITH CONVOLUTE.

Good info! I've decided to keep my truck out of the dealer until I see some more TSBs out. Mine is definitely associated with 2nd gear and shifts to and from gears 1 and 3. Everything else is fine. I just don't want to load up my vehicle carfax with service issues just yet.

 

Well guys, I think I’m the first of us to have been towed to the dealer! What a father's day I had... Brand new 2011 F150 3.5L Ecoboost FX4 Crew with 6.5' box. Only 1,000 miles on it before my first tow. I have a roughly 7,000lb camper. Truck towed awesome to the campsite. I did notice the shudder when taking off, but only towing. On the way home I noticed a cloud of white smoke billowing out of the rear. I pulled over and noticed tranny fluid dumping on the ground. All over the under-side of my truck and on the camper. I limped to the next exit about a mile away and called the tow truck. I had gears still, so it can't be too bad. Didn't notice a crack in the case at all. Prior and during there were no temp spikes at all... trans temp was reading normal. Could have busted a line, or fitting... or maybe even the stupid drain plug wasn't tight from the factory, who knows.

My dealer just called me and will be looking into it. I did tell them about the shudder as well. I'll keep everyone updated.

(At least it was a Ford towing a Ford!)

 

Man that sucks! Sorry to hear your Fathers day was ruined. Please keep us all posted and good luck.

 

Definitely more serious than some shudder!

I took mine to the dealer today. They're getting with engineering. They want to check pinion angle & correct/change. We'll see...........

 

Picked it up today, engineering had them put a one degree shim for pinion angle. Didn't help. Ford engineer wants to look at it Friday.

 

This is describing a totally different issue then I'm having.

thanks anyway

 

Okay, sorry about my last post. I would like to help since if the probelm is trans related it will spread to all trucks.
Questions for those with the issue:
1. If the traction control is turned off, is the shudder present when towing or under load?
2. If the traction control and advance trac are turned off, is the shudder present?
3. Is the shudder present when the trans fluid is cool or only once it warms up?
4. Is the shudder present when the trans is shifted manually by placing the shifter in M and shifting it at higher rev points?
5. If the traction control, advance trac are turned off and the tow/haul button is depressed is the shudder still present?
These are important questions that we all would like answered to help. They all connect to the shift program that ford uses and identifies if the shift program has too low of pressures or if the converter is locking and unlocking between gears. I am asking this since the manual says the converter is not locked up until higher gears when the tow/haul button is pressed. If the shudder is shift related, then the pressures are too low or the converter may be engaging at too low of a speed and in too low of a gear. Lets trouble shoot where the dealer won't because the techs don't get paid to fix a part, just replace it.
