P07F6 on Ford by model: symptoms, diagnosis and fix
On some Explorers with the 10R60 ten-speed automatic, engagement into gear or shifts can be harsh or delayed, sometimes with the check-engine light on and transmission codes stored. Ford attributes it to transmission-control software, the solenoid ID strategy and/or sticking valves in the main control valve body. It affects 2020–2023 Ford Explorers equipped with the 10R60 ten-speed automatic that show the symptoms or codes listed in bulletin 23-2352 (the bulletin also covers 2020–2023 Aviator and 2021–2023 Bronco with the 10R60).
Common Symptoms
- Harsh or delayed engagement into gear
- Harsh or delayed shifts
- Check-engine light on with transmission codes stored
How to Fix
Have a Ford dealer confirm the symptom and check for later PCM/TCM software. Bulletin 23-2352 specifies a PCM/TCM software update and adaptive learning drive cycle first. If the condition remains and one of the listed codes is stored, the main control valve body is serviced; without codes, vehicles built on or before 1-Nov-2021 first get a transmission solenoid strategy reprogram, and later builds go to the valve body. Ford notes shifts can feel firmer than normal for several days while the adaptive strategy relearns. Normal warranty rules apply; this is not a recall or a promise of free repair.

Frequently asked questions
What does P07F6 mean on a Ford?
P07F6 stands for "Gear 9 Incorrect Ratio." Generic transmission code in the extended gear-ratio series (P076F = gear 7, P07D9 = gear 8, P07F6 = gear 9, P07F7 = gear 10), used on 9- and 10-speed automatics. The transmission control module compares input shaft speed to output shaft speed while 9th gear is commanded; if the calculated ratio does not match the expected value, it sets this code. Symptoms can include slipping, flaring or harsh shifts at highway speeds, failure to reach top gears, or the transmission dropping into limp mode. Because it can indicate internal clutch wear, do not just clear it and keep driving — have the fluid condition and the shift data checked. On Ford it is documented across 1 model: Explorer.
What are the most common causes of P07F6?
The most common causes of P07F6 are: Low, burnt, or contaminated transmission fluid, Worn or slipping clutch pack for the affected gear, Failed or sticking shift solenoid, or a valve body/solenoid pack fault, Input or output speed sensor fault, or damaged speed sensor wiring, giving a false ratio, Internal mechanical wear or debris in the transmission, Transmission control module fault or software needing an update (verify mechanical condition first). The specific cause varies by vehicle.
How much does it cost to fix P07F6 on a Ford?
Repair costs vary widely with the root cause and Ford model; each issue on this page carries its own estimate where one is published.
