A critical issue affecting the transmission valve body of certain Ford Bronco, Explorer, F-150, Mustang, Ranger, and Lincoln Aviator vehicles can cause reverse gear failure or unexpected forward movement while in reverse or neutral gear. This problem could be a significant safety risk to drivers and passengers.
According to Ford, the issue is attributed to an incorrectly machined transmission valve body, specifically the Outer Valve Body (OVB) of the transmission main control. The machining tool used during production did not maintain proper specifications, resulting in out-of-specification dimensions that can prevent the vehicle from entering reverse gear when commanded by the gear shift module.
Symptoms of the problem include no reverse motion when the gear selector is in reverse, and in some cases, the vehicle may move forward with the gear selector in either reverse or neutral position. The Malfunction Indicator Light (MIL) and Wrench light will illuminate on the dashboard when this malfunction occurs.
The recall affects vehicles, including:
- 2024-2025 Ford Bronco
- 2025 Ford Explorer
- 2024-2025 Ford F-150
- 2025 Ford Mustang
- 2024 Ford Ranger
- 2025 Lincoln Aviator
Ford’s investigation into the matter began in February 2025, after a transmission failure was reported on a 2025 Mustang at the Flat Rock Assembly Plant. The company subsequently issued a Stop Ship order for affected models and launched an analysis of the suspect transmissions.
Using advanced data analytics, including Machine Integrated Learning and Optimization (MILO) modeling, Ford identified individual Outer Valve Body units that were likely to experience this condition. The company then conducted evaluations of vehicles equipped with suspect parts and confirmed the symptoms reported by customers.
As of February 21, 2025, Ford had received five warranty reports related to this issue. On March 7, 2025, the company’s Field Review Committee approved a field action, which includes replacing the transmission main control valve body.
Ford has notified owners of affected vehicles and has begun repairing the transmissions. The recall is identified as Ford’s number 25S19 and NHTSA Campaign Number 25V-164.
This recall highlights the importance of rigorous quality control measures in the automotive manufacturing process. The issue serves as a reminder that even minor defects can have significant consequences on vehicle safety and performance.
