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.

Truck has 11K miles. When breaking at low speeds, I get a lot of break squeal. This happens driving forward or in reverse. Also, when driving the truck has a hard time shifting and makes a rattling/pinging noise when it is trying to find the correct gear. This happens sporadically when driving slow, fast, uphill, and mostly occurs during acceleration. The shifting issue happens on the freeway as well as city streets.
