2006 GMC Yukon Shift Interlock Solenoid

The shift lock control system is only active when the ignition switch is in the run or on position. this means that when the ignition switch is in the run or on position, the shift lever cannot be moved out of the park position without activating the brake.

You need to pull out the tab on the adjuster block side of the shift lock control actuator, press on the adjuster block to compress the internal adjuster spring which disengages the adjuster teeth, slide the adjuster block, and lock the adjuster block in place.

You need to disable the SIR system, remove the body control module (BCM), put the shift lever clevis into the neutral position, disconnect the electrical connector, pry the automatic transmission shift lock control actuator away from the steering column jacket and the cable shift cam, and remove the shift lock control actuator.

You need to remove the transmission filter and the 1-2 accumulator, disconnect the internal wiring harness electrical connectors, remove the pressure control solenoid retainer bolt and retainer, the pressure control solenoid, the 1-2 shift solenoid retainer and the 1-2 shift solenoid, the 2-3 shift solenoid retainer and the 2-3 shift solenoid, the 3-2 control solenoid retainer and the 3-2 control solenoid.
