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.

My ABS light keeps coming on in my 2004 ford expeditionxlt. It has been doing it for a while. I had the upper control arms and lower ball joints replaced in the front and it stopped for a while now it has started again. I've had some vibration in my brakes right as the ABS light comes on. Can anyone shed some light?

#27 of 31 vehicle jerks while breaking
Sep 08, 2011 (4:37 am)
I have a 06 expedition with 75K miles. Recently it has started to jerk, or kind of lunge forward when the brakes are applied. It does this continually while the brakes are applied. Wondering if this is the transmission issue that I have been reading about on here or something to do with the brakes?

I have a 07 Expedition EL with 74K and it is doing the lunging thing sometimes. I don't know if it's brakes or trans. I can be applying the brakes and put the truck into neutral while it is doing the lunging and it doesn't change. I would assume that if the truck isn't in drive then it wouldn't be the trans. The truck isn't under warranty anymore or I'd take it to the dealer. Do you have any suggestions?

What do you mean by "doing the lunging thing sometimes"? That isn't really a description of anything. Do you mean while slowing down you feel pulsation? If that is the case it is likely warped rotors.Have you ever had the brakes done? Rotors?

In the message board, "while braking to a stop the vehicle has a lunge to it" with steady rpms and with steady braking. It's not a vibration from rotors, those would do it all the time in the same conditions, this feels like someone is pumping the brakes only you don't feel it in the pedal. This truck only does it after it seems to warm up, or been driven several miles which kinda points me in the direction of a transmission problem more than an ABS problem. But this is why I tried braking with the vehicle in neutral and the problem continued. I'm thinking I have a ABS problem now and I'm just trying to figure out if this is a brake shop issue or a transmission shop issue.
