Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Range Selector Switch
The switch is mounted inside the transmission main case on the driver's side. This location provides precise monitoring of the Manual valve position and is sheltered from the harsh environment under the vehicle external of the main case. Adjustment is not required. The range selector switch has 6 wires. The GS 20 provides the switch with 12 volts on one wire (pin 2 of connector X70004). Depending on the range selector position, the switch provides coded high signals over five wires to the GS 20. The addition of the fifth wire (pin 1) is new compared with previous four wire range selectors providing a redundant P/N signal circuit. See Fig 1 .
