Ford F-150 Recall: What 2015–2017 Truck Owners Should Know About the Transmission Downshift Issue

Ford has issued a formal safety recall (NHTSA Recall 26V237, Ford Recall 26S28) for certain 2015 through 2017 F-150 pickup trucks equipped with the 6R80 six-speed automatic transmission. The recall addresses a condition where an intermittent signal loss from the Transmission Range Sensor can cause the transmission to unexpectedly downshift into second gear, which may cause the rear wheels to slide or lock up momentarily.

The recall affects approximately 1,392,935 F-150 trucks. Separately, Ford has a Customer Satisfaction Program (26N04) for transmission molded leadframe replacement on the same vehicles. Both actions address the underlying transmission lead frame condition, but the recall specifically addresses the safety risk of unintended downshifts.

What the Recall Addresses

Degradation of the electrical connections in the transmission lead frame due to thermal cycling and vibration can result in an incorrect signal from the Transmission Range Sensor to the Powertrain Control Module. This can cause the transmission to command an unintended downshift from sixth gear directly to second gear, which can cause the rear wheels to momentarily slide or lock up, increasing the risk of a crash.

Ford is aware of 444 warranty claims, 121 field reports, 105 customer service reports, and 316 owner complaints potentially related to this condition, representing two injuries and one accident.

What the Recall Does

The recall addresses the unintended downshift condition through a PCM software update. It does not automatically cover every transmission issue on every 2015–2017 F-150. The lead frame replacement under the Customer Satisfaction Program is limited to vehicles that exhibited specific diagnostic trouble codes before the software update.

Which Vehicles Are Affected

The recall covers certain 2015, 2016, and 2017 Ford F-150 trucks equipped with the 6R80 six-speed automatic transmission, built between March 12, 2014, and August 18, 2017. Not every truck within those model years is necessarily included. Eligibility depends on your VIN and the transmission installed.

Your VIN is the only reliable way to confirm whether your truck is included. Do not assume coverage based on model year or trim level alone.

What to Gather Before Contacting a Dealer

• Your VIN and current mileage.
• Service records, especially any transmission inspections, fluid changes, software updates, or repairs.
• Invoices for paid transmission work, with dates and mileage noted at the time of service.
• Any owner notification letters you may have received from Ford regarding this recall.
• Any history of warning lights - specifically the wrench light or transmission-related warnings, as this may indicate whether the lead frame replacement is needed.

Having these documents ready makes it easier to have a specific conversation with the dealer instead of a generic one.

How to Get a VIN-Specific Answer

Contact an authorized Ford dealer and provide your VIN. Ask the dealer to check:

• Whether your truck is included in Recall 26V237 (Ford Recall 26S28).
• Whether the PCM software update has been completed.
• Whether the lead frame needs to be replaced under the Customer Satisfaction Program (26N04) if diagnostic trouble codes were present before the software update.

If you are told the recall does or does not apply, save that response with the truck's service records. A written summary from the dealer creates a useful paper trail.

What the Fix Involves

Dealers will update the Powertrain Control Module (PCM) software at no cost to the owner. This update prevents unintended downshifts by changing how the control system recognizes a degraded or intermittent sensor signal.

If an affected vehicle previously exhibited certain diagnostic trouble codes related to this condition before the software is installed, dealers will replace the transmission lead frame under the Customer Satisfaction Program (26N04), also at no cost.

If You Paid for a Related Repair

If you have already paid for a transmission repair that may fall under the Customer Satisfaction Program, bring those invoices to the dealer. The program may allow for review of prior paid repairs, but the outcome depends on the specific documentation and the program's terms.

Do not assume the dealer will automatically reimburse prior work. Request a written determination.

Bottom line: This is a formal safety recall - not just a voluntary program. If you own a 2015–2017 F-150 with the 6R80 transmission, check your VIN now. An unintended downshift is a serious safety risk. The dealer can update the PCM software and, if necessary, replace the lead frame at no cost.
