What does P0750 mean?
This code comes from the transmission control system. Shift solenoids route fluid to apply clutches and change gears.
The computer tried to control the part and saw an electrical fault, usually an open circuit.
Codes are a starting point. They tell you which test failed, not which part to replace. Check for other stored codes and fix those in a sensible order.
Symptoms
- Check engine light
- Harsh, late or erratic shifting
- Transmission stuck in one gear (limp mode)
- Flare between gears
Common causes
- Open circuit in the solenoid or its wiring
- Unplugged or corroded connector
- Blown fuse feeding the component
- Failed component
How to diagnose P0750
- Check the fuse that feeds the component.
- Measure the component's resistance and compare it with the service spec.
- Check for power at the connector with the key on, and for a broken control wire back to the computer.
- Check fluid level and condition using the correct procedure for your transmission.
- Read codes from the transmission module itself, not just the engine computer.
How to fix it
- Correct the fluid level and service the fluid
- Repair wiring
- Replace the solenoid or valve body
- Repair or replace the transmission if worn
Estimated repair cost
Likely repairs for P0750 run from about $150 to $5,500, depending on the cause.
| Repair | Typical range (parts + labor) |
|---|---|
| Diagnostic fee (scan + testing) | $100 - $200 |
| Transmission fluid and filter service | $150 - $400 |
| Transmission solenoid / solenoid pack | $300 - $900 |

These are rough US estimates for an independent shop in 2026, based on typical parts prices and standard labor times. Dealers, big trucks, luxury brands and high-cost areas often run higher. They are not quotes. Use the repair cost estimator to adjust for your vehicle.
How serious is P0750?
High severity
Limp mode often locks the transmission in one gear. Drive gently and only as far as the shop.
