Shift Interlock Solenoid For Chevy, GMC, Hummer, Saab – Replaces 924-978, 88967140 | Fits Trailblazer, Envoy, H2, H3

Stuck in 'Park'? This shift interlock solenoid is a super common fix for a bunch of GM SUVs and trucks. It replaces part numbers 924-978, 924978, and 88967140. Fits a ton of vehicles: Chevrolet Trailblazer (2002-2009) and SSR, GMC Envoy, Buick Rainier, Oldsmobile Bravada, Saab 9-7X, and Hummer H2, H3, and H3T models from the early 2000s to about 2010. This little part is a safety device – it's what lets you shift out of park only when your foot is on the brake. If it fails, you might not be able to shift at all, or you might hear a buzzing/clicking sound from the shifter area. Installing a new one restores that function. It comes as a complete unit, ready to swap in. Installation is usually pretty simple – a couple of screws and an electrical connector. Just make sure your specific model is listed. Amrxuts tests these parts for quality, so you're getting a reliable replacement that won't break the bank compared to the dealer part. Get your gear shift freedom back!
