Lincoln Aviator · 2020–2023
Some 2020-2023 Lincoln Aviators equipped with a 10R60 and built on or before December 23, 2022, or a 10R80 MHT and built on or before August 15, 2022, may have harsh or delayed engagement and/or harsh or delayed shifts. Ford TSB 22-2428 says the condition may involve PCM/TCM software, the transmission solenoid-ID strategy, sticking main-control valves, or axial movement of the CDF clutch-cylinder sleeve. The complaint may occur with or without a malfunction indicator and the bulletin's listed transmission DTCs. The symptom alone does not select a valve body, CDF cylinder, or complete transmission.
Common Symptoms
- Harsh engagement
- Delayed engagement
- Harsh shift
- Delayed shift
- Malfunction indicator with a bulletin-listed transmission DTC
How to Fix
Have a Ford/Lincoln-capable technician confirm the transmission and build date, retrieve PCM/TCM faults, and follow TSB 22-2428 in order. The bulletin begins with available PCM/TCM programming and an adaptive-learning drive cycle, then uses the stored faults and clutch behavior to select an accelerated main-control break-in routine. If the condition remains, the procedure can require main-control overhaul and, only after the bulletin's later tests fail, condition-specific internal transmission repair. Parts and coverage must be selected by VIN and the actual failed step; this record intentionally has no buy link.
Owner tips & cautions
- TipRecord the exact shift or engagement event and ask for the PCM/TCM fault report plus the TSB decision-tree step that failed before approving internal transmission work.
- WarningDo not order a valve body or CDF part from harsh shifting alone; Ford's procedure can resolve the condition through programming, adaptive learning, or clutch cycling before parts are selected.

Frequently asked questions
What does P07F7 mean?
P07F7 stands for "Gear 10 Incorrect Ratio." Generic (SAE-defined) powertrain code for vehicles with 10-speed automatic transmissions, most commonly the Ford 10R60/10R80 and GM 10L80 family. It is part of a series where P07F6 is Gear 9 and P07F7 is Gear 10. The transmission control module compares input shaft speed to output shaft speed and found that the actual ratio in 10th gear did not match the ratio it commanded. In practice the driver may feel harsh or delayed engagement, harsh or delayed shifts, flare on the shift into top gear, or the transmission may refuse to reach 10th at all. Because slipping clutches generate heat and debris, this should be diagnosed rather than cleared and ignored.
What are the most common causes of P07F7?
The most common causes of P07F7 are: Slipping clutch pack for the 10th gear element due to wear, Low or degraded transmission fluid, Internal hydraulic leak - on Ford 10R60/10R80 units, axial movement of the CDF clutch cylinder sleeve/bushing is a documented cause addressed by Ford service bulletins, Stuck or failing shift solenoid or valve body bore wear, Faulty input or output shaft speed sensor giving a false ratio calculation, Outdated transmission control module calibration. The specific cause varies by vehicle.
How much does it cost to fix P07F7?
Repair costs vary widely depending on the root cause and vehicle.
