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.

Grand Prix GTP 3.8L V6 Supercharged

  • Automatic transmission

This car has had the typical problems with the blower motor and the clogged condensate drain tube and now I find out that this trans problem is also typical of this car. The dealer is no help and I may have to put out big bucks to replace the trans. I will buy a Honda next time.
