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.

Transmission has rough downshifts while decelerating. First rough downshift occurs around 40-45 mph. The second rough downshift occurs around 25 mph. During the second rough downshift, it feels as though the transmission is shifting twice. You can also hear a distinct clack noise and feel it through the floorboard of the vehicle. Transmission software updated twice but problem still exists. We also experience abrupt deceleration when removing your foot from the accelerator around 30 mph. The van slows down abruptly as though the engine has stalled. We feel the transmission behavior is a safety issue because you do not know what level of engine/transmission braking will occur when you take your foot off of the accelerator. This makes you feel uncomfortable driving the vehicle.
