• Q: How to service and repair the Shift Interlock Solenoid on 2008 Chevrolet Express 2500?

  A: Start the servicing and repair of the Shift Interlock Solenoid by disabling the Safety Interlock Release system. The first step requires setting the shift lever clevis to neutral position and then removing the knee bolster. Start by disconnecting the electrical connector after which you must pry the A/T shift lock control actuator off from its mount points on the steering column jacket assembly and the cable shift cam assembly before removal. The installation process requires proper attachment of the A/T shift lock control actuator against the steering column jacket assembly and the cable shift cam assembly with electrical connector reconnection. To adjust the actuator with the shift lever clevis in neutral position follow these steps: reach for the tab found on the adjuster block side then compress the block by applying force before sliding it as far from the actuator as possible and complete the adjustment by tab engagement. The actuator needs examination to confirm its ability to lock the shift lever clevis in park position and enable movement out of park through brake pedal reduction while receiving power. Reposition the actuator when needed and replace the knee bolster before enabling the SIR system.
