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.

I know a transmission is a wearable item - they don't last forever. However, I have never in my life seen a trans bite the dust at 120k miles! I don't even tow regularly either - maybe half a dozen times light loads under 2000 lbs. Cost me a fortune to fix.

Suburban LS 5.3L

  • Automatic transmission
  • 147,000 miles

When my transmission was rebuilt, the re builder replaced the sun shells with factory improved units that werte available from Chevrolet before my truck was ever even made. I never used it for towing, so it was never worked really hard that is except for my size 15 foot{no, it really is} on the throttle, but if they knew the original design was bad, weak or flawed in some way bad enough to make better ones then why the hell did they not install them to begin with???????? I will still only ever buy American cars as they are still the bestespeciall if you are a real man and over 6'6" and 320, and also add to it that if these stupid fellow Americans of mine really want to help the economy get better, then start buying more things made here inh America rather than somewhere else ESPECIALLY WHEN IT COMES TO CARS, MORONS!!!!!!

This is unacceptable and makes me want to never buy another American made car....money only goes to make CEO's rich and the parts/vehicle cheaper because the Top is only interested in enriching themselves at the expense of American consumers!!!!
