Gear Switches

Gear switches are located inside automatic transmission. Switches may be normally open or closed and change status depending upon internal hydraulic pressures. High gear switch information is used by ECM in controlling emission components and engagement of Viscous Converter Clutch (VCC) on 4.9L or Torque Converter Clutch (TCC).
