Code P0750 on the 2024 Ford Explorer indicates a malfunction in shift solenoid A. This transmission solenoid controls hydraulic flow for specific gear changes. When the solenoid or its circuit fails, the transmission cannot properly control those gear selections.
Shift Solenoid Function
Automatic transmissions use solenoid valves to direct hydraulic fluid and engage clutch packs for different gears. Shift solenoid A typically controls the 1-2 shift or related circuits depending on transmission design. The transmission control module (TCM) commands solenoid operation based on vehicle speed and driver input.
P0750 Effects
With shift solenoid A malfunctioning, you may experience harsh or delayed 1-2 shifts, the transmission may skip or get stuck in certain gears, or the vehicle may go into limp mode (limiting to one gear). The check engine light illuminates and transmission warning messages may appear.
Common Causes
Solenoid electrical failure (open or shorted coil) is common. Low or contaminated transmission fluid affects solenoid operation and can cause similar symptoms. Wiring issues between the TCM and solenoid pack, connector problems in the harsh transmission environment, or TCM driver circuit issues can also cause P0750.
Diagnostic Approach
Check transmission fluid level and condition first. Test solenoid resistance at the connector. Command solenoid operation through scanner and verify function. Many solenoids are accessible in the valve body without complete transmission removal.
