Replace a failed transmission control solenoid without paying for a complete valve body with the Standard Ignition Transmission Control Solenoid TCS401. It is a direct-fit OE replacement for the 2011-2023 Ford F-250 Super Duty, F-450 Super Duty and F-550 Super Duty, along with select Ford F-350 Super Duty, F-53 Motorhome Chassis, F-650 and F-750 years.
A transmission control solenoid is an electrically operated valve. When the vehicle's control module commands it, the solenoid helps route transmission fluid through passages in the valve body.
- Avoid a full valve body replacement: If the solenoid is the failed component, you can replace just the solenoid and skip the cost of a complete valve body.
- Direct-fit OE replacement: Designed for easier installation on a repair that is often difficult and time-consuming.
- High-quality materials: Built to withstand extreme conditions.
- Rigorously tested: Standard Ignition's Quality Assurance Team runs extensive testing aimed at reliability.
A solenoid may need replacing if you notice harsh, delayed or erratic shifting, or transmission-related trouble codes. Other faults can cause the same symptoms, so diagnose the cause before replacing the part.

Frequently Asked Questions
What does this transmission control solenoid do?
It is an electrically operated valve. When the vehicle's control module commands it, the solenoid helps direct transmission fluid within the valve body.
Which vehicles does the TCS401 fit?
It is listed for the 2011-2023 Ford F-250, F-450 and F-550 Super Duty, plus select Ford F-350 Super Duty, F-53 Motorhome Chassis, F-650 and F-750 years. See the "Vehicles it fits" section for engine details.
What are signs of a failing automatic transmission control solenoid?
Possible signs include harsh, delayed or erratic shifts and transmission-related trouble codes. Other faults can cause similar symptoms, so diagnose the cause before replacing the part.
Do I have to replace the whole valve body?
Not necessarily. If the solenoid itself has failed, installing this direct-fit OE replacement lets you avoid the cost of replacing the complete valve body.
What part numbers does the TCS401 interchange with?
The Standard Ignition TCS401 interchanges with TCS324, TCS944 and BC3Z7G383L.
