Just sold my silverado and do not need these any longer. They are THE manuals that the dealerships use to service vehicles, you can completely tear a vehicle down and put it back together again with these, also has torque specs, troubleshooting, wiring diagrams, diagnostic trouble code break downs, etc etc. I used these manuals a couple times installing my remote start, transmission shift kit, and installing my mcgaughy's drop kit. They cover the following vehicles: Silverado, Tahoe, Surburban, Sierra, Yukon, Yukon XL
