Shiftlock Control Without Cruise Control

The system consists of the following components:

• The stoplamp switch
• The shift lock solenoid

When the vehicle is in PARK, the transmission range switch is closed and ignition voltage is supplied to the stoplamp switch. When the brake pedal is applied, the stoplamp switch closes and battery voltage is applied to the shift lock solenoid which energizes and releases the locking tab on the floor shifter.
