With DTC P07F7 And Loss Of 10th Gear
This bulletin supersedes 21-2323. Reason for update: Remove the vehicle production fix date
Model:
Ford
2020 F-Super Duty
Engine: 6.2L/7.3L
Transmission/Transaxle: 10R140
Summary
This article supersedes TSB 21-2323 to remove the vehicle production fix date.
Issue: Some 2020 F-Super Duty vehicles equipped with a 6.2L or 7.3L engine and a 10R140 transmission may
exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P07F7 stored in
the powertrain control module (PCM) and a loss of 10th gear. The vehicle may also exhibit harsh engagements and
poor shift quality. This may be due to the sleeve in the CDF clutch cylinder shifting axially causing hydraulic circuit
leaks. To correct the condition, follow the Service Procedure to replace the CDF clutch cylinder.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
• 2020 F-Super Duty
• 6.2/7.3L gas engine
• DTC P07F7 stored in the PCM
• Loss of 10th gear

5. Assemble the C, D and F clutch assemblies into the new CDF clutch cylinder.
6. Perform the C, D and F clutch pack endplay measurements for proper clearance.
7. To reassemble the clutch and planetary assembly, reverse the removal procedure. Refer to WSM, Section 307-01
> Overhaul.
8. Perform the T3 thrust bearing measurement to set transmission front end clearance.
9. Reassemble the transmission starting at Step 299 in WSM, Section 307-01 > Overhaul.
10. Install the transmission. Refer to WSM, Section 307-01.
NOTE: For 7.3L applications, if the exhaust hanger bracket bolts are not available, apply Motorcraft®
Threadlock 262 to the threads and reuse the exhaust hanger bracket bolts.
11. Perform an adaptive learning drive cycle. Refer to WSM, Section 307-01.
NOTE: Advise the customer that this vehicle is equipped with an adaptive transmission shift strategy which
allows the vehicle's computer to learn the transmission's unique parameters and improve shift quality. When
the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may
result in firmer than normal upshifts and downshifts for several days.
