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 car develops a rumbling vibration when the auto tranny shifts gears and usually when the car attains a cruising speed. I disengaged the over drive but results are the same. It also happens when I use cruising control; and always when the speed and acceleration are at cruising mode. Feedback welcome.
