2006 Chevrolet Silverado 2500HD LT3 4dr Crew Cab 4WD LB (6.0L 8cyl 4A)


I think I bought a Monday morning vehicle. The rear differential leaks, and I get abhorrent fuel mileage. 8 MPG when towing a 7500 pound trailer and adequate mileage not towing (16 MPG) I took it to the the Chevy dealership twice for the leaking problem. It happens when driving it on the highway or towing. They added an inline filter in the breather hose, not much help, it slows the process down until the filter fills up, then it leaks out of the tube. The third time I take it to a different dealer, they replace the inline filter with a smaller one and the want to re-tap a new location for the breather tube right on the rear axle housing and plug up the old one on top of the pumpkin.

Best Features

Power seats for front passenger and heated seats for both passengers.

Worst Features

The hydromatic shift for the allison 6 speed should be on the steering wheel for ease of shifting instead of on the face of the gear shifter which places it behind the steering wheel. It's not ergonomically sound.
