POWER TRAIN
SAFETY HAZARD & RISK The 10R80 transmission exhibits sudden, unpredictable gear slipping, power loss, and violent slamming/lunging during gear shifts while navigating active traffic. This erratic behavior creates an immediate collision risk when merging, accelerating, or changing lanes, as the truck unexpectedly loses momentum or lunges forward. INCIDENT & REPAIR HISTORY The vehicle required two complete transmission overhauls under 68,000 miles at Apple Ford (Columbia, MD), both confirmed by certified technicians and warranty inspectors: Overhaul #1 (Invoice #273111 Aug 14, 2024 42,571 miles): Diagnosed under TSB 24-2101 for shift failure. The dealer overhauled the valve body and replaced internal components, including the CDF drum (Part #JL3Z7H351B). Overhaul #2 (Invoice #351672 Sep 11, 2026 67,587 miles): Less than 25,000 miles later, severe slipping and 5th gear binding recurred. Teardown revealed a sticking main pressure control valve, burnt E & F clutch packs, and an outdated CDF drum. The dealer replaced the complete valve body (Part #JL3Z7A100CRM), installed a redesigned CDF cylinder (Part #PC3Z7B177A), and replaced scorched clutch/steel plates.
