P0750: Shift Solenoid A Malfunction
Can you still drive? Not recommended for extended driving. The transmission may be stuck in one gear or shifting harshly. Drive only to a repair facility.
What Does P0750 Mean?
Code P0750 indicates an electrical or functional problem with shift solenoid A, which is one of the solenoids responsible for controlling hydraulic fluid flow to engage specific gear sets. Shift solenoids are electro-hydraulic valves inside the transmission that direct fluid pressure to apply or release clutch packs and bands. When solenoid A fails, the transmission cannot shift properly into certain gears.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

- Failed shift solenoid A
- Wiring short or open in solenoid circuit
- Corroded transmission connector
- Faulty TCM solenoid driver
- Contaminated transmission fluid clogging solenoid
Symptoms
- Check engine light on
- Transmission stuck in one gear
- No upshift from 1st gear
- Harsh or delayed shifting
- Transmission in limp mode
Diagnostic Steps
- 1Read all transmission codes to identify which solenoids are affected
- 2Check transmission fluid for debris and contamination
- 3Measure shift solenoid A resistance at the transmission connector
- 4Test solenoid operation with scan tool bidirectional control
- 5Inspect transmission wiring harness and connector
- 6Drop transmission pan and inspect solenoid for contamination

ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
Ford Motor Company (Ford) is recalling certain 2021-2026 F-150, 2022-2026 F-250 SD, F-350 SD, F-450 SD, F-550 SD, Maverick, 2024-2026 Ranger, 2023-2026 F-600 SD, 2022-2027 Lincoln Navigator, Expedition, and 2026 E-Transit vehicles. When towing a trailer, the integrated trailer module (ITRM) may lose communication with the vehicle, possibly causing a loss of brake and turn signal lights, or a loss of brake function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, " Lamps, Reflective Devices, and Associated Equipment."
Remedy: The integrated trailer module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters are expected to be mailed March 17, 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26C10.

Frequently Asked Questions
What is a shift solenoid?
A shift solenoid is an electro-hydraulic valve inside the transmission controlled by the TCM. It opens and closes to direct transmission fluid pressure to specific clutch packs, enabling gear changes.
Can dirty transmission fluid cause a shift solenoid code?
Yes. Contaminated fluid can clog the solenoid valve or leave deposits that prevent it from opening and closing properly. Regular fluid changes help prevent this.
Can I replace just one shift solenoid?
On some transmissions, individual solenoids are replaceable. On others, they come as a complete solenoid pack that must be replaced as a unit. Check your vehicle's service manual.
