Tackle a shifting problem without replacing the entire valve body using the Standard Ignition Transmission Control Solenoid TCS408. It installs as a direct-fit OE replacement on many vehicles, among them the 2021-2023 Ford F-650, 2016-2019 Ford F-750 and 2011-2020 Ford F-350 Super Duty. See the "Vehicles it fits" section for the full list.
This automatic transmission control solenoid is an electrically operated valve. The vehicle's control module switches it to direct transmission fluid within the valve body, which helps manage how and when the transmission shifts.
- Solenoid-only repair: When the solenoid is the failed component, replacing just this part can spare you the cost of a complete valve body.
- Direct-fit OE replacement: Designed for easier installation on what is often a difficult, time-consuming repair.
- High-quality materials: Built to stand up to extreme operating conditions.
- Tested for reliability: Standard Ignition's quality assurance team puts these solenoids through extensive, rigorous testing.
Signs this part may need replacing: harsh, delayed or erratic shifts, slipping, a transmission stuck in one gear, or a check engine light with transmission-related codes. Diagnose the cause first. If a faulty solenoid is behind the symptom, this part replaces it.

Frequently Asked Questions
What does a transmission control solenoid do?
It is an electrically controlled valve that the vehicle's control module switches on and off. It directs transmission fluid within the valve body, which helps manage shift timing and engagement.
Which trucks does TCS408 fit?
It fits many Ford trucks, among them the 2021-2023 Ford F-650, 2016-2019 Ford F-750 and 2011-2020 Ford F-350 Super Duty. See the "Vehicles it fits" section for the full list.
Do I need to replace the whole valve body?
Not necessarily. If diagnosis confirms this solenoid is the failed component, replacing it on its own can help you avoid the cost of a complete valve body.
What are signs of a failing transmission solenoid?
Harsh, delayed or erratic shifts, slipping, being stuck in one gear, or a check engine light with transmission codes can signal a solenoid problem. Confirm the cause before replacing parts.
What part numbers does TCS408 interchange with?
TCS408 interchanges with TCS331, TCS951 and BC3Z7G383V.
