Are you sure they followed this? Take it back.
DRIVELINE BUMP WHILE BRAKING - BELOW 10 MPH (16 KM/H)
This article supersedes TSB 08-4-13 to update the Issue, Service Procedure and remove the production fix date.
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.
Follow the Service Procedure steps to correct the condition.
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.
#122 of 243 transmission clunking under hard acceleration
Sep 05, 2009 (9:57 am)
I appreciate your help on a 98 expedition which causes aloud banging noise from the transmission area while under hard acceleration. The fluid is clean and filled correctly. The truck shifts fine and drives fine under normal acceleration, but when you try to give gas in order to pass or get off in a hurry from the pack the trans. does some serius banging.

Sep 13, 2009 (11:59 pm)
hi, i have an 01 expy. and the truck will not go into gear unless i crawl under the truck and un-plug the tranny position senser wires, witch does not bother me as much as the fact that the truck wont start again when you shut it off, unless you crawl back under the truck and plug the wires back in............ has anyone ever had this problem, and if so what did you do to fix it. thanks alot in advance for your help

I also have this problem! I went to Lemon Law Arbitration and the Ford Rep totally lied and the Judge believed him. I have since put Ford on Notice of a Dangerous and Defective condition. By doing this, I have put Ford on the hook if this condition creates an accident. So, if anyone does get into an accident because of this condition, you can now sue Ford because of me.
Please feel free to do this yourself. I only have 6 months left on my lease and I too will never again buy a Ford product. Between myself and my husband we have owned approximately 8 Ford vehicles. If this is the way they treat loyal customers, I don't want any part of it!

So the Ford rep totally lied: what did he say?
#126 of 243 RPM Question
Sep 26, 2009 (8:58 pm)
I have an 06 Expedition XLT that will not rev up past 3500 RPM's. It happens while in park or driving. I was passing a car on a two lane road when I first noticed it. Once it gets to 3500 it feels like a governor is in place and it will rev between 3000 and 3500.
Any ideas on what would cause this?
#127 of 243 08 Expedition-"Scraping" noise
Oct 07, 2009 (5:59 am)
Truck bought new and only have 14,000 miles. The other day after a trip of about 400 miles, noticed a slight scraping noise from underneath when accelerating usually below 30 mph.
Only does it for split second and don't notice any slippage, just the odd noise. Doesn't do it every time so dealer probably won't be able to replicate.
Any ideas before we take it to dealer?

Figure out how to make it 'scrape' consistently. Then take the service rep on a test drive. It's not normal. There is a TSB for a sqawk noise on hard accleration at around 30mph, but it sounds like a belt slipping, not scrapping. Could be related though. Here is the info for that.
6R75 TRANSMISSION - SQUAWK NOISE DURING
This article supersedes TSB 08-19-8 to update the vehicle model years and remove the production fix date.
Some 2007-2008 Expedition vehicles equipped with a 6R75 transmission may exhibit a squawk type noise during hard acceleration down shifts (4-3), (5-3) and (6-3) downshifts. The noise is produced during the release of the overdrive clutch.
Follow the Service Procedure steps to correct the condition.
Follow Workshop Manual (WSM), Section 307-01B to replace the overdrive friction plates.

after using my 4x4 in reverse I switched it over to 2wd but it will not go back to 2wd instead it is still in 4wd, it is driveable but when you release the gas pedal the rpms go to idle no matter how fast you are traveling, help thanks
Oct 15, 2009 (5:42 am)
Actually it may not be driveable. If it is stuck in 4WD and you make tight corners on dry pavement you are risking damage to the drive line. Sounds to me like the transfer case shift motor didn't move out of 4WD.
