There are multiple TSB's on this issue. It has nothing to do with anyone's driving style. The reflash cured my massive clunk coming to a stop-as loud as a sledge hammer against a sheet of steel.

Well, I guess that my expedition must have been reflashed before I purchased it because my tranny has never made big clunky noises.

(I sure am sorry if I offended some of you by mentioning driving habits as a way to prevent a hesitation from occurring when starting from a stop or near stop.)

No worries. I just wanted people to know this is a problem with the transmission and not something to do with the 'adaptive' technology that others have blamed the transmission problems-slipping, clunking, lurching, not shifting into 1st gear- on.




TSB 08-22-7

11/10/08

DRIVELINE BUMP WHILE BRAKING - BELOW 10 MPH (16 KM/H)
FORD:
2007-2008 Expedition

This article supersedes TSB 08-4-13 to update the Issue, Service Procedure and remove the production fix date.
ISSUE
Some 2007-2008 Expedition vehicles may exhibit a bump feeling while braking to a stop below 10 MPH (16 Km/h). This procedure will improve the bump felt while braking to a stop.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
CAUTION APPLYING THIS PROCEDURE TO UNITS THAT DO NOT EXHIBIT THE COASTDOWN BUMP MAY RESULT IN WORSE SHIFT QUALITY.

NOTE DO NOT ATTEMPT TO REPLACE THE MECHATRONIC UNIT. MECHATRONIC REPAIR/REPLACEMENT IS NOT AUTHORIZED FOR THIS ISSUE.

1. Install Integrated Diagnostic System/Portable Diagnostic Software (IDS/PDS) or equivalent and ID the vehicle.

2. Update the Power Control Module/Transmission Control Module (PCM/TCM) calibration using IDS release 57.8 and higher or 58.1 and higher. This new calibration is not included in the VCM 2008.9 DVD. Calibration files may also be obtained at the website. Since the TCM cannot be independently reprogrammed, reprogram the PCM to ensure that engine and transmission calibrations are updated to the latest level simultaneously.

a. Verify that the TCM shows 8L1P-7J104-AC (8L1P-7J104-BC for 2008 vehicles built after 12/3/2007) part number after reprogramming is complete.

b. Select the following from IDS, Tool Box, Powertrain, OBD Test Modes, Mode Level 9 Vehicle info, TCM Cal Part Number.

3. Clear TCM keep alive memory (KAM) and adaptive tables.

a. Using IDS:

(1) Open Toolbox.

(2) Choose Powertrain.

(3) Choose Reset KAM.

(4) Then Choose TCM.

b. Using PDS:

(1) Choose all Tests and Calibrations.

(2) Scroll down the menu and choose reset TCM KAM.

NOTE FOR PDS, RESET TCM KAM IS NOT THE SAME AS CLEAR TRANSMISSION ADAPTIVE TABLES, WHICH IS UNDER THE POWERTRAIN - TRANSMISSION MENU TREE.

NOTE UNHOOKING THE BATTERY WILL NOT CLEAR THE TCM KAM.

NOTE DO NOT CLEAR THE PCM KAM.

4. Verify that the transmission fluid temperature (TFT) PID is above 175 F (80 C). If it is not at 175 F (80 C), drive unit approximately 3 miles (5 Km) to reach temperature.

NOTE TFT MUST BE AT 175 F (80 C) OR ABOVE BEFORE PROCEEDING TO STEP 5.

5. Drive unit to perform adaptive shift strategy learn:

a. Accelerate from rest with light throttle to 15 MPH (24 Km/h), remove foot from accelerator pedal.

b. Brake very gently to a complete stop (allow at least six (6) seconds).

c. Repeat Steps (a-b) a total of five (5) times in the dealership parking lot or similar setting.

d. Accelerate from rest with light throttle ensuring that the 1-2, 2-3 and 3-4 shifts occur at engine speeds between 1300-1800 RPM.

e. Continue to accelerate until you achieve 50 MPH (80 Km/h) or the 5-6 upshift.

f. Brake gently to a complete stop and hold foot on brake for at least 10 seconds.

g. Repeat steps (e-f) three (3) times.

NOTE THE HARSH BUMP FELT WHILE BRAKING TO A STOP WILL BE IMPROVED. HOWEVER, SEVERAL DAYS OF DRIVING ARE REQUIRED FOR THE TRANSMISSION TO FULLY ADAPT.

WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage IMPORTANT: Warranty coverage limits/policies are not altered by a TSB. Warranty coverage limits are determined by the identified causal part.

I'm looking at a 2007 tomorrow that is still in the factory drivetrain warranty. If the trans. needs to be flashed, is that covered under the drivetrain warranty?

Yes it is. I think there was one person who paid for the 'service' of that who shoudn't have. Any work done to the drive train is covered, except spark plugs, filters, etc.

Notice how it shifts as you come to a stop and take off.

My 2010 has started the deceleration thump. I notice it most in traffic and moving through parking lots and drive thrus.. Really disappointing as I thought these issues would not show up on a 2010.. Will start the repair saga when I get my first oil change.

If the thump is noticeable I wouldn't wait. Some wear is happening.

I have also noticed that with the 2010 vs my 2007 I feel I slight rumbling in certain gears kind of like when you shift to soon with a manual transmission, how it rumbles until you get up to speed. I thought 4 years later they would have these transmissions figured out, guess I was wrong.. At least it does not do the rolling stop 2-1 jump like my 07, for now anyways..

I had just a couple of downshift bumps that were corrected with the reflash.
I took it in for an audible squeak or grunt on upshift some 20K ago (39K on clock now) but dealer was unable to duplicate.
Problem seems to happen more under heavy load (towing), but not always.
While towing my 5k# trailer this weekend, I mashed the pedal to pass and the transmission squeaked so loud my wife asked if I honked the horn!
I thought it might have been a transmission temperature problem, but tranny temps were <185F. I have the 7yr/100k warranty so I'll just make sure I take care of it before then.

That's the friction plates. I have had mine replaced twice. They last about 30K. Drive it slightly up hill at 30mph, let off the gas then floor it so it down shifts. Get to where you can do it anytime, take the tech on a test drive. The TSB is 09-06-01.

Sorry to revive an old thread....
But I was wondering if anyone finally concluded a fix for the transmission?
I still own my truck it has turned over 122k miles. It's been a great truck and never experienced any of the issues for transmission until now. I'm getting that noticeable thunk and a hard kick at hard acceleration.

Trying to figure out if this is going to be a costly fix or sadly to say I'm going to trade it in on a new truck unfortunately it may not not be a Ford this time around.

63,500 miles currently. Once in a blue moon, while coasting at highway speeds I will experience the tranny acting as though it is in neutral for a seconds and then it will thunk in to gear. I can't duplicate it and it has never done it to my wife (it's her daily driver).
My original issue had to do with a clunk during deceleration. A module was changed at 15,000 miles and that issue went away . good luck.

It feels like the truck never down shifted itself to 1st geard and its trying to pull away in 2nd or 3rd. It will evertually kick down and find the correct gear but it can be scary especially when making a left in front of on coming traffic. Is this related to the problem you all are describing?
berry1234- mine (07 with 100k) does the above ^. Even worse, it has occasionally stayed in second or third after shifting from park to drive whilst trying to pull the boat out of the water, and almost beginning to roll backwards despite applying plenty of rpm.......disconcerting to say the least!!!

Usually, shifting manually to first eliminates this, but not always.... I just tell the wife to not "***** foot" around when pulling the boat and I up the ramp. ie I tell her pretty much "stomp it" if it begins fishing around for first.

I had the dealer service the tranny, and presumably re-flash it, but to no avail. ( they said that they do look for TSBs before a sevice....)

Do you know if there a separate TSB regarding this- ie the tranny not going down to 1st after a stop or incomplete stop or shifting from park to drive??

If there's one out there, I'd like to hear about it too. Wife's 07 has been doing this since we bought it used a few years ago, but only if we don't come to a full and complete stop...and even then, not all the time. Shifting manually to first pretty much ensures it doesn't happen, but I'd like to see if we know what the problem is.

I put a tube of Lubeguard Trans Fluid Additive. Dr. Tranny Instant Shudder Fixx, it has fix my shuddering problem. I know it probably has not addressed anything that may be major, but it worked!
