Adaptive Cruise Control problems of the 2019 Ford Ranger

The vehicle is experiencing a severe power train failure involving erratic and violent gear selection. The transmission unexpectedly jumps from 2nd, 3rd, or 4th gear directly up to 7th or 8th gear, resulting in a total loss of acceleration. This is immediately followed by the transmission "slamming" down into lower gears, usually 1st or 2nd gear without driver input. This behavior is accompanied by a strong burning smell and a dashboard "wrench" warning light. The symptoms match the manufacturing defect documented in Ford TSB 24-2101 (cdf clutch drum). Diagnosis & manufacturer response: the issue began in October 2025 with a noticeable transmission shudder. I paid for two transmission flushes at big o tires to attempt to resolve the issue, but the mechanical failure has since escalated. When the "wrench" light appeared, an independent diagnostic computer was unable to retrieve an error code, as the light is a proprietary Ford powertrain indicator. Furthermore, the wrench light clears upon restarting the vehicle, despite the violent shifting and burning smell remaining. Ford corporate agents claim there are "no known issues" and have refused to assist with towing, despite an active NHTSA engineering analysis (pe 24-001) regarding this exact 10r80 transmission. Safety risk: this defect creates an extreme safety hazard. Violent downshifting into low gears at highway speeds can cause a loss of vehicle control or a rear-end collision. The burning smell indicates internal friction and fluid oxidation, posing an immediate fire risk or the potential for a catastrophic mechanical lock-up.
