6R60-6R75 TRANSMISSIONS - REPLACEMENT
REQUIREMENTS - JOB 1 ONLY

FORD:
2008 Expedition, Explorer Sport Trac, Explorer

MERCURY:
2008 Mountaineer

ISSUE
The 2008 Explorer Sport Trac, Mountaineer, Explorer 4dr vehicles that were built on or before 11/29/2007 and Expedition vehicles that were built on or before 12/3/2007 were built with a unique transmission assembly. Only the later (Job-2) transmission design will be available as a service replacement. The later transmission design has internal changes that are incompatible with previous calibrations. If transmission replacement is required then a coordinated powertrain control module (PCM)/ transmission control module (1CM) reprogramming will be necessary to support these changes of internal hardware.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

The transmission serial number is located on the driver side lower left side behind the manual lever: Refer to Workshop Manual (WSM), Section 307-01A.

^ Job-1 8L2Z-7000-C will be replaced by Job-2 8L2Z-7000-E (4x2) 6R60

^ Job-1 8L2Z-7000-D will be replaced by Job-2 8L2Z-7000-F (4X4) 6R60

^ Job-1 8L1Z-7000-A will be replaced by Job-2 8LiZ-7000-C (4X2) 6R75

^ Job-1 8L1Z-7000-B will be replaced by Job-2 8LiZ-7000-D (4X4) 6R75

NOTE
VEHICLES THAT HAVE USED THIS PROCEDURE, ANY FUTURE PCM REPLACEMENTS WILL REQUIRE TRANSMISSION SERIAL NUMBER IDENTIFICATION FOR IDS REPROGRAMMING SELECTIONS.

Follow Work Shop Manual for Transmission Replacement Procedure.

NOTE
VEHICLES REFERENCED IN THIS ARTICLE ARE EQUIPPED WITH A PCM AND TCM, AND REQUIRE A COORDINATED FLASH. THIS COORDINATED FLASH PROCEDURE MUST BE FOLLOWED EXACTLY AS OUTLINED BY THE IDS. FAILURE TO FOLLOW THE KEY CYCLE PROCEDURE WITHOUT WAITING FOR THE IDS PROMPTS, WILL CAUSE THE COORDINATED FLASH TO FAIL. THE PCM WILL BE UPDATED BUT THE 1CM WILL NOT BE UPDATED AND THE NEW FILES WILL NOT BE INSTALLED. IT IS CRITICAL TO FOLLOW THE IDS PROMPTS TO ENSURE A PROPER REPAIR.

1. Install IDS/PDS or equivalent and ID the vehicle.

2. Update the PCM/TCM calibration using IDS release 55.11 and higher or 56.1 and higher. This new calibration is not included in the VCM 2008.7 DVD. Calibration files may also be obtained at the website. Since the TCM cannot be independently reprogrammed, reprogram the PCM using the "PMI" function to ensure that engine and transmission calibrations are updated to the latest level simultaneously. Verify TCM shows correct part number after reprogramming is complete.

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 1CM 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 the unit to perform adaptive shift strategy learn.

a. Accelerate from a stop 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) five (5) times in the dealership parking lot or similar setting.

d. Accelerate from a stop 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 10 seconds.

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