The 2022 Ford Explorer triggering P0750 indicates a malfunction with shift solenoid A in the 10-speed automatic transmission. This three-row SUV's sophisticated transmission uses multiple solenoids for gear selection, and solenoid A affects first-gear operation.
Understanding P0750
P0750 indicates an electrical or performance problem with shift solenoid A. This solenoid helps control hydraulic fluid flow for gear engagement. Problems can be electrical (circuit issues) or mechanical (stuck valve).
Explorer 10-Speed Transmission
The 2022 Explorer uses a 10-speed automatic transmission (10R80). This transmission uses multiple electronically-controlled solenoids to achieve its wide gear range. Solenoid A is part of the gear selection system.
Shift Solenoid Function
Shift solenoids are electrically-operated valves that direct transmission fluid to engage clutches and bands for gear changes. Solenoid A typically affects lower gears. Malfunction can cause harsh shifts, slip, or inability to engage certain gears.
Common Causes
Electrical failure within the solenoid. Dirty fluid clogging solenoid. Wiring issues between TCM and solenoid. Valve body problems affecting solenoid operation. Transmission fluid level or condition issues.
Fluid Inspection
Transmission fluid condition significantly affects solenoid operation. Dark, burnt, or contaminated fluid can cause solenoid issues. Check level and condition before extensive diagnosis.
Repair Costs
Transmission fluid service costs $200-400. Individual solenoid replacement runs $300-700 (requires valve body access). Complete valve body replacement ranges $1,000-2,000. Transmission rebuild exceeds $3,500.
