While driving from [XXX] to [XXX] on XXX my 2021 Ford Ranger's dash light came on and I noticed harsh shifting and the vehicle began jolting unpredictably while I was driving at highway speeds. To avoid imminent danger, I pulled off the 101 and slowly drove to the closest Ford dealership, Vista Ford Lincoln of [XXX], in order to have the truck assessed. Technicians performed a diagnostic evaluation and retrieved DTC P0766 (shift solenoid "D" performance/stuck off) and P2703 (transmission friction element "D" apply time.) These codes are the documented engineering signature of internal CDF clutch drum bushing migration- a known, widespread manufacturing defect inherent to Ford's 10R80…
The contact owns a 2020 Ford Escape. The contact stated that the vehicle failed to reverse while the transmission was shifted into reverse(R). The transmission and check engine warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with diagnostic trouble code (DTC): P0766 (Shift Solenoid "D" Performance/Stuck Off) and the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact related the failure to Technical Service Bulletin: 21-2421 (FWD - 1.5L - 8F24 Transmission - No Reverse Engagement with DTCs P0766 And P2703) however, the vehicle was not covered under the TSB. The failure…
Harsh shifting into D, loss of power when accelerating while cold. Sometimes would start across an intersection then buck, loose power and slow down then SLAM back into gear and chirp the rear tires. Technical Service Bulletin 23-2350 was performed on 11/15/2023 which updated the trans tables and cleared some codes. This helped the issue for about a week but then truck was in again on 1/22/2024 for TSB 23-2350 a second time which replaced the CDF drum. A month later, 800 miles, 2/18/2024 truck shifted HARD while in cruise control on the turnpike in traffic and lost power. DTC P0766 check engine light came on and truck would no longer move. Transmission fluid sprayed under truck. Had to be…

What should I do if my car shows P0766?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
