2017 Ford F-150: shudder or vibration when accelerating

Filed Sep 10, 2026 · Transmission · KY

The torque converter has malfunctioned and the vehicle is currently at the dealership for repairs. The truck experiences significant vibration and shuddering at speeds above 45 mph. There is an existing recall for this exact issue; however, our VIN is not included in the affected vehicle population. With only 60,000 to 70,000 miles on the truck and less than 10 years of service, a major component such as the torque converter should not require replacement, especially on a vehicle that has been properly maintained throughout its life.

The 10-speed transmission exhibits severe and dangerous shifting behaviors. It frequently shudders and jerks extremely hard when shifting between gears.Most critically, the transmission fails to properly engage into gear. While driving, I came to a complete stop at a red light in active traffic. When the light turned green and I attempted to accelerate, the transmission would not engage into gear, leaving the vehicle completely immobilized and just sitting there in the middle of traffic. Because the truck failed to take off and move forward, it created an immediate road hazard and almost caused me to be severely rear-ended by the traffic behind me.This transmission hesitation and failure to engage poses an immediate and severe safety risk of a high-speed collision.

I've had the transmission replaced under fordprotect warranty and subsequently another torque converter and subsequent to that, a new program installed to repair low RPM Shudder. Under mild acceleration at interstate speeds (65 TO 75 mph) it now hunts for gears with random upshifts and downshifts while failing to maintain or increase speed which constitutes a safety hazard.
