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.

problem #1

Sierra 1500 SLT 5.3L

  • Automatic transmission
  • 50,952 miles

I have to say that I am not to impressed that the transmission needed overhauled at such low km's but I am lucky that I have a family member that owns one of the finest tranny shop around and was able to look after me! He also told me that 3 and 4 usually go at about 150,000km so he replaced everything now at 82,000km truck runs great now!
