Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Silverado 2500 HD LS 6.0L

  • Automatic transmission
  • 49,000 miles

I have a 06 silverado with a 6.0 that won't pull , It didn't have this problem when I first bought it but once it started I haven't been able to find a fix. I have been thinking its a motor power problem maybe transmission. when I am not pulling anything to go up hill and try to keep a speed between 50 and 70 is impossible to hold the pedal in one place speed quickly falls off, from there I have to punch it it shifts into passing gear and if I put it in cruise it will hold the speed but it will shift up and down the whole way. To pull a local hill with my sport quad I only get 6 MPG can only do 55mph completely punched and it shifts in and out of passing gear very frequently. I am a mechanic and have done all the basic matinenance and still no fix. Talk about a gutless truck.

Silverado 2500 HD LS 6.0L

  • Automatic transmission
  • 45,000 miles

I have an 06 Silverado 2500 with the 6.0. I have taken it to dealerships to several local shops and no one can tell me why I have a hard time pulling one sport four wheeler. When I first got it I could pull anything and still get decent mileage. now best 6 MPG with my one wheeler...Before this I got 14 MPG and 11 or so while pulling now 12 at best and 6 MPG while pulling ANYTHING. I have been told my converter is not plugged, I have done a tune up. Its ridiculous I even put a aftermarket intake on it and it actually made it worse. The first five minutes I could tell a great difference but then the computer changed the settings and it mad the power even worse. My next step is to get a programmable chip to see if that fixes it.

(reported on)

Silverado LT3 5.3L

  • Automatic transmission
  • 12,000 miles

paid the extra money for the bigger motor, truck runs like a 4 cyl. will not kick down after 70 mph,

2006 5.3l does not run comparable to previous years 2000-2004's

truck feels very sluggish and takes forever to get up to freeway speeds.
