Shop transmission control solenoids built to keep your automatic transmission shifting smoothly and on schedule. These electro-hydraulic solenoids regulate fluid flow inside the valve body, controlling shift timing, torque converter lockup, and line pressure — and a failing one is a common cause of harsh shifts, delayed engagement, slipping, or a transmission stuck in limp mode. Find reliable replacements for cars, trucks, and SUVs to restore precise, on-time shifting.
