2001 GMC Savana 1500 Shift Interlock Solenoid

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

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 automatic transmission shift lock control actuator, press on the adjuster block to compress the internal adjuster spring, slide the adjuster block, and lock the adjuster block in place by pushing in on the tab.
