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.

: the contact stated while traveling 20 mph the transmission made a noise while it was changing gears. At first the noise was a light ping but now the noise had become regressively worse. The sound graduated to a clunk. The vehicle was taken to a dealer where the contact was alerted that a letter from the manufacturer indicated that the vehicle could not be fixed. The noise was a characteristic of the way the vehicle was manufactured. Updated 9/28/2006 -
