A transmission control solenoid is an electrically operated valve. The transmission control module energizes it to direct fluid within the valve body, and the transmission uses that fluid to manage its shifts.
This solenoid may need replacing if you notice harsh, delayed or erratic shifts, a transmission that stays in one gear, or transmission-related diagnostic trouble codes. Other transmission faults can cause these same symptoms, so diagnose the cause before you replace parts.

What does an automatic transmission control solenoid do?
It is an electrically operated valve. The transmission control module energizes it to direct fluid within the valve body, and the transmission uses that fluid to manage its shifts.
Which vehicles does the TCS412 fit?
It fits the 2011-2023 Ford F-250, F-450 and F-550 Super Duty, the 2011-2020 and 2022 Ford F-350 Super Duty, and select Ford F-53, F-650 and F-750 years. See the Buyer's Guide tab for full details.
