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.

When switching into overdrive hear a loud clunking so can only drive in 3rd gear, also intake manifold is leaking antifreeze in crankcase oil. Any recommendations on getting assistance from GM regarding recall on these defective parts?

Any recommended repairs before they tell me I need a new engine?
