TECHNICAL SERVICE BULLETIN 25-2023
Harsh/Delayed Engagement And/Or Harsh/Delayed Shift 07 Fepray
This bulletin supersedes 24-2101. Reason for update: update the vehicles affected, Service Procedure, and parts list
Model:
Ford Transmission/Transaxle: 10R80
2018-2021 Expedition
Lincoin Transmission/Transaxle: 10R80
2018-2021 Navigator
Markets: North American markets only
Summary
Issue: Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions:
+ Harsh engagement
+ Delayed engagement
+ Harsh shift
+ Delayed shift
+ Illuminated MIL with DTCs P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771,
P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733,
P0734, P0735, P0736, PO76F, PO7D9, PO7F6 and/or P07F7 stored in the PCM or TCM
This may be due to axial movement of the CDF clutch cylinder (7H351) sleeve causing hydraulic circuit leaks.
NOTE: If internal transmission service is required to address a concern detected with the CDF clutch
cylinder following this article, technicians should carefully inspect and replace other transmission
components and flush transmission fluid cooler only as necessary to confirm proper function. Add a new
line to the repair order to document any additional repairs needed. M-time can be claimed on the additional
repair line to cover labor. Refer to Warranty and Policy Manual for additional information. A thorough
understanding of transmission description and operation will assist the technician with proper diagnosis,
inspection, and successful repair of the customer concern.
NOTE: The Pressure Vacuum Transducer Kit (Rotunda 164-R9833) and VCMM Transmission Extension Kit
(Rotunda 164-R9534) recommended to perform this article are no longer included with the VCMM Advanced
Kit (Rotunda 164-R9823), and were discontinued in July 2023. Ford has confirmed a high percentage (80%) of
Dealers have this equipment available to perform this article. Refer to Table 1 in the Service Procedure for
equipment alternatives. In addition, VEMM Universal Probe Tip Adapter (Rotunda 164-R9834, or equivalent)
is needed to perform this article. The Probe Tip Adapters are included in VCEMM Advanced Kit (Rotunda 164-
R9823).
Action: For vehicles that meet all of the criteria in the Issue and Model statements, follow the Service Procedure to
verify hydraulic circuit leakage and replace the CDF clutch cylinder (7H351) if necessary.

Service Procedure
1. ls a VCMM pressure transducer available?
(1). Yes - proceed to Step 2.
(2). No - proceed to Step 21.
2. Install the YVCMM pressure transducer to the transmission line pressure port. (Figure 1)

NOTE: Some vehicles may require the removal of the transmission park manual release cable and bracket to
gain access to the line pressure plug. Refer to WSM, Section 307-01 > Transmission Line Pressure Test.
NOTE: The line pressure port is an M10X1.0 thread. Do not use a National Pipe Thread (NPT) fitting when
installing pressure reading equipment. If an NPT fitting is used, damage to the transmission case will occur.
NOTE: The transmission extension hose kit requires a 1/4 in. Joint Industry Council (JIC) male adapter.
NOTE: All NPT fittings must be assembled with polytetrafluoroethylene (PTFE) tape or paste to prevent leaks
* VCMM Transmission Extension Kit
* Locally obtain the necessary adapter fittings to connect the VCMM pressure transducer to the transmission line
pressure port (Figure 2)

3. Prepare the TM connector C1822 to be back probed by removing the connector cover. Access to the LPG
solenoid circuit CET50, Pin 15, WH-OG wire is required in a later step.
4. Using the latest software level of the FDRS and VCMM, start a session.
5. Using EDRS select the following PIDs.
* PCM -RPM_DSD #
¢« VCMM - PVT Pressure (set scale to +/- 3447 kPa)
° IGM-TFT
* TCM -SSA_AMP#
* TCM - SSB_AMP #
+ TCM-SSC_AMP #
* TCM -SSD_AMP #
* TCM -SSE_AMP #
¢ TCM -SSF_AMP#
6. Does the vehicle exhibit harsh/delayed engagement and/or harsh/delayed shift symptoms only when TET is at
50°C (122°F) or below?
(1). Yes - perform Step 7 while TET is between 35-50°C (95-122°F).
(2). No - perform Step 7 while TET is at 50°C (122°F) or above.
7. Start the engine and enter Live Display mode. Verify the vehicle is in P with the emergency brake applied and TET
is at the appropriate temperature identified in Step 6.
(1). In the settings menu, under the capture tab, set capture timings to duration: 25, pre: 10, post: 15.
(2). For each step below, highlight the PID to enable it and select #. Then control the PID with up/down arrows.
(3). Command SSA_AMP #/SSB_AMP #/SSC_AMP #/SSD_AMP #/SSE_AMP #/SSF_AMP # to OmA.

(4). Decrease RPM_DSD # between 500-600 rpm.
(5). Obtain maximum transmission line pressure by using a VCMM Universal Probe Tip Adapter (Rotunda 164-
R9834, or equivalent) along with a suitable multimeter lead wire and probe (Figure 3) to back probe the LPC
solenoid circuit CET50, Pin 15, WH-OG wire at the TCM connector C1822 and use the multimeter lead wire and
probe to ground the circuit. (Figure 4) Once line pressure is at maximum (1900-2000kPa or 275-290 PSI) the
ground probe is no longer needed to maintain maximum line pressure.
