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. Notes: Ahh, the ole' sophomore slump. The 2008 Acadia suffers from widespread transmission failure around 75,000 miles.

This is the second time I have had the same issue. I am driving the vehicle and the transmission does not shift out of 2nd gear. The check engine light comes on. I have the vehicle repaired once for this issue. I was told it was the valve body the first time and it was replaced out of warranty.
