Duralast Automatic Transsmision Pressure Switch Manifold PS667

The Duralast line of vehicle electronics is designed for original equipment (OE) form, fit and function for both import and domestic vehicles. The Transmission Switch reports transmission pressures to the on-board computer, and when pressure is low, will illuminate the check engine light. When not replaced, vehicle operators may not be notified of transmission pressures falling below critical limits. In more advanced vehicles, an unreplaced faulty transmission switch or sensor may not notify on-board computers of critical system pressure, thus not allowing the computers to protect the transmission from any damage.
