2022-2024 Ford/Lincoln 10R80 Harsh Shifts TSB 26-2408

Owners of various 2022-2024 Ford and Lincoln vehicles equipped with the 10R80 transmission may notice a concerning issue: Ford F-150 harsh shifts and/or harsh reverse engagement. This problem is particularly noticeable when the vehicle is cold. Ford has released Technical Service Bulletin (TSB) 26-2408 to provide a diagnostic and repair procedure for this condition.

This bulletin, TSB 26-2408, supersedes a previous version, TSB 26-2309, and includes updated model information and parts lists. The primary focus of this TSB is to address the underlying mechanical issue causing the harsh transmission behavior.

Symptoms

If your vehicle is affected, you may experience one or more of the following symptoms, which tend to be more pronounced when the transmission fluid is cold:

• "Harsh 3-4, 4-5 upshifts"
• "Harsh 5-3, 4-3 downshifts"
• "Harsh reverse engagements"

These symptoms indicate that the transmission is not shifting smoothly between gears or engaging reverse properly, leading to an uncomfortable driving experience.

Cause of the Problem

The root cause of these Ford F-150 harsh shifts and reverse engagement issues has been identified as the "F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177)". Brinelling refers to indentations or damage caused by excessive force or wear, which can prevent proper clutch operation within the 10R80 transmission.

Important Warnings / What Owners Should Know

Ford advises that the 10R80 transmission is equipped with an adaptive shift strategy. This means the vehicle's computer learns the transmission's unique parameters to optimize shift quality. When the adaptive strategy is reset as part of a repair, the computer will begin a relearning process. This relearning period may result in shifts that are firmer than normal for several days following the repair. Owners should be aware of this temporary change in shift feel.

Repair Procedure Summary

The repair procedure outlined in TSB 26-2408 involves a comprehensive overhaul of specific transmission components to correct the brinelling issue. The steps are detailed and require specialized knowledge and tools.

1. Fluid Filter Removal: The first step is to remove the transmission fluid filter, following the guidelines in the Workshop Manual (WSM), Section 307-01. This provides initial access for inspection.
2. Silt Inspection: Technicians must inspect the top side of the transmission fluid filter for any signs of gray silt, which can indicate internal wear or contamination. Figure 1 in the TSB illustrates what to look for.
3. Diagnostic Check: If gray silt is present, the repair proceeds. If no silt is found, the TSB may not apply, and further diagnosis for normal transmission issues is recommended.
4. Fluid Pan Reinstallation (Temporary): The transmission fluid pan and bolts are reinstalled temporarily. It is specifically noted that it is not necessary to torque the transmission fluid pan bolts at this stage.
5. Transmission Removal: The entire transmission assembly is then removed from the vehicle and mounted onto a workbench for detailed work, as per WSM, Section 307-01.
6. Main Control Valve Body Removal: The main control valve body is removed from the transmission, following WSM, Section 307-01.
7. Valve Body Overhaul: The main control valve body is then thoroughly overhauled, which includes cleaning and inspection of its components, referencing WSM, Section 307-01.
8. Transmission Disassembly: The transmission is disassembled, focusing on removing the clutch and planetary assembly. Only specific components need to be removed at this stage, including the transmission fluid pan, fluid pump, auxiliary pump (if equipped), and all four speed sensors (intermediate speed sensor A [ISSA], intermediate speed sensor B [ISSB], TSS, and OSS).
9. Clutch and Planetary Disassembly: The clutch and planetary assembly itself is disassembled. This involves removing the clutch and planetary container cylinder, the CDF clutch cylinder, the No. 3 sun gear shaft, and the No. 2 ring gear assembly. Specific sub-steps include:
   • Removing the A clutch assembly, selective shim, and T3 thrust bearing, and discarding the 5-input shaft front seals.
   • Removing the No. 1 planetary carrier snap ring, the clutch and planetary container cylinder, the No. 4 ring gear snap ring, and the No. 4 ring gear. The clutch and planetary container cylinder is discarded.
   • Removing the E clutch and input shaft assembly, the No. 3 planetary carrier and No. 3 sun gear, the No. 3 sun gear shaft, and the No. 2 ring gear assembly.
10. Sun Gear Shaft Seals (Discard): The sun gear No. 3 shaft seals are removed and discarded.
11. Sun Gear Shaft Seals (Install): Four new sun gear No. 3 shaft seals are installed.
12. F Clutch Plates (Discard): The F clutch steel plates and friction plates are removed and discarded from the CDF cylinder.
13. F Clutch Plates (Install): New F clutch steel plates and friction plates are installed into the CDF clutch cylinder.
14. F Clutch Pack Measurement: The F clutch pack endplay is measured to ensure proper clearance.
15. Input Shaft-to-Sun Gear Seals (Discard): The input shaft-to-sun gear No. 3 shaft seals are removed and discarded.
16. Input Shaft-to-Sun Gear Seals (Install): Five new input shaft-to-sun gear No. 3 shaft seals are installed.
17. Input Shaft Teflon Seal (Discard): The input shaft Teflon seal is removed and discarded.
18. Input Shaft Teflon Seal (Install): A new input shaft Teflon seal is installed.
19. Input Shaft Front Seals (Install): Five new input shaft front seals are installed.
20. Ring Gear and Snap Ring (Install): The No. 4 ring gear and snap ring are installed into a new clutch and planetary container cylinder.
21. Clutch and Planetary Reassembly: The clutch and planetary assembly is reassembled by reversing the disassembly procedure.
22. Transmission Reassembly: The transmission is reassembled.
23. Transmission Installation: The transmission is reinstalled into the vehicle.
24. Adaptive Learning Drive Cycle: An adaptive learning drive cycle is performed to allow the transmission's computer to re-learn optimal shift parameters.

Labor Times

Labor times for this repair vary significantly depending on the specific vehicle model, engine type, drivetrain (4X2, 4X4, RWD, AWD), and whether the initial fluid filter inspection passes or fails. For example, a 2022-2024 Explorer 3.3L 4WD Hybrid that passes the fluid filter inspection might take 2.3 hours (Operation No. 262408A), while one that fails and requires the full valve body overhaul and F clutch replacement could take 13.9 hours (Operation No. 262408B). Similarly, a 2022-2024 F-150 4X4 3.5L PowerBoost failing inspection could require up to 15.1 hours (Operation No. 262408C5).
