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, P076F, P07D9, P07F6 and/or P07F7 stored in the PCM or TCM .
This may be due to axial movement of the CDF clutch cylinder 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 (PVT) 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) since July 2023. Supply of the PVT Kit (Rotunda 164-R9833) and VCMM
Transmission Extension Kit (Rotunda 164-R9534) have been sold out. Ford has confirmed a high percentage (80%) of Dealers have this equipment available. Alternatively, Ford has tested suitable transmission fluid pressure gauges and developed procedures which reliably enable the capability to perform this article. Refer to Table 1 in the Service Procedure. In addition, VCMM.
Universal Probe Tip Adapter (Rotunda 164-R9834, or equivalent) is needed to perform this article. The Probe Tip Adapters are included in VCMM
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, if instructed, replace the CDF clutch cylinder and the clutch and planetary container cylinder.

- Is a VCMM
PVT available?
- Yes - proceed to "DIAGNOSTIC PROCEDURE A - VCMM PVT IS AVAILABLE ".
- No - proceed to "DIAGNOSTIC PROCEDURE B - NO VCMM PVT AVAILABLE ".
DIAGNOSTIC PROCEDURE A - VCMM PVT IS AVAILABLE
- Install the VCMM
PVT to the transmission line pressure port. (Figure 1)NOTE: The line pressure port Is an M 10X1.0 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)
ITEM DESCRIPTIONItem Description 1 M10X1.0 male to 1/8 in. FNPT female 2 1/8 in. NPT male to 1/4 in. JIC male 3 Extension hose - VCMM

- Prepare the transmission LPC
solenoid circuit CET50 to be back probed at either the TCM
/PCM
connector or at the transmission electrical connector by removing the connector cover. Access to the LPC
solenoid circuit CET50, WH-OG wire is required in a later step. Refer to Wiring. Cell 029 Transmission Controls and the video link at the start of the Service Procedure in this article.NOTE: Back probing the LPC solenoid circuit will set a DTC and Illuminate the powertrain malfunction (wrench) Indicator.
- Using the latest software level of the FDRS and VCMM , start a session.
- Does the vehicle exhibit harsh/delayed engagement and/or harsh/delayed shift symptoms only when TFT
is at 49°C (121°F) or below?
- Yes - when prompted in Step 5. choose the FDRS option for the transmission shift concern occurs when the TFT is at or below 49°C (121°F).
- No - when prompted in Step 5, choose the FDRS option for the transmission shift concern occurs when the TFT is at or above 50°C (122°F).
- Select and run the FDRS
Transmission Clutch Circuit Leak Test, follow FDRS
screen prompts and directions to proceed.
- When prompted, choose the transmission fluid temperature identified in Step 4.
- When prompted, ground the LPC circuit 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 and ground the VCMM solenoid circuit CET50. (Figure 4) Once line pressure has elevated and stabilized, the ground probe is no longer needed to maintain elevated line pressure.
ITEM DESCRIPTIONItem Description 1 VCMM universal probe adapter 2 Multimeter lead wire 3 Multimeter lead wire probe - Test is complete. Release control of all parameters then turn ignition off.
- Remove back probe from the LPC circuit connector and reinstall the connector cover.

- Did the transmission test results pass?
- Yes - this article does not apply. Refer to WSM , Section 307-01 for normal diagnostics.
- No - (field displays red) - proceed to "REPAIR PROCEDURE " in this article.
DIAGNOSTIC PROCEDURE B - NO VCMM PVT AVAILABLE
- Install a suitable transmission fluid pressure gauge that measures at least 300 PSI (2,000 kPa) with vibration dampening to the line pressure port (Figure 1) Refer to Table 1.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: All NPT fittings must be assembled with polytetrafluoroethylene (PTFE) tape or paste to prevent leaks.TABLE 1 - FORD TESTED SUITABLE TRANSMISSION FLUID PRESSURE GAUGES, OTHER SUITABLE GAUGES MAY BE USED
