Frequently Asked Questions

Can recalibrating the actuator fix P0901?

In some cases, performing a clutch actuator calibration procedure can resolve the range/performance issue, especially after a clutch replacement or fluid service.

Is the PowerShift transmission known for this code?

Yes, the Ford PowerShift DCT is well documented for clutch actuator and shudder issues. Ford extended warranty coverage for many affected vehicles.

Does the clutch need to be replaced with the actuator?

Not always, but if the clutch disc is worn thin, it should be replaced at the same time to avoid needing to remove the transmission again shortly after.
