What P0750 means
A shift solenoid is an electrically switched valve in the valve body. Manufacturers use these codes differently: Ford reports an open circuit with the base code and shorts separately, newer GM units have separate low/high codes, and the letter is not tied to a valve number (Saab's 9-5: A = valve S2). P0750 is the general code for solenoid A and is used in practice for an open circuit: Ford's step automatics (2012–2023) set it when the smart driver feedback disagrees with the command for 0.5–5 s, with shorts to ground and power as P0973/P0974; Ram's 6.7 L with Aisin transmission calls it 'control circuit open', and a 2023 bulletin traces it to a leaking capacitor in the engine module. GM does not use P0750. With the solenoid unpowered the transmission falls back to a hydraulic default gear with maximum pressure.
P0750 at a glance

- Emissions testCan fail
- Limp modePossible

- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0750
- Check engine or transmission warning lamp
- Limp mode in a fixed gear, no upshifts
- Harsh shifts from maximum line pressure
Common causes of P0750
- Most likelyOpen or corroded wire or transmission pass-through connector
- PossibleSolenoid coil open or shorted
- PossibleInternal harness or electronic module in the transmission
- Less likelyModule driver faulty or valve supply missing
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0750 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 50 | The exact fault in that area. |
What to do next
- Note P0750 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0750
What does P0750 mean?
P0750 means "Shift Solenoid A". A shift solenoid is an electrically switched valve in the valve body. It is a generic code, so it means the same on every make.
Is it safe to drive with P0750?
Drive gently and only to a workshop. With P0750 the car can go into limp mode (reduced power) to protect itself.
Will P0750 fail an emissions test?
Yes, it can. P0750 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0750 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0750 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
