A transmission control solenoid is an electrically operated valve. The vehicle's control module energizes it to direct transmission fluid, which helps manage when and how the automatic transmission shifts.
Signs this part may need replacing include harsh, delayed or erratic shifting, a transmission that stays in one gear, or a check engine light with transmission-related codes. Other faults can cause the same symptoms, so diagnose the cause before replacing any parts. If a failed solenoid is the cause, the TCS95 replaces it.
