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.

Bought the car april 06 used with 120,000 miles on it. Test drove, it ran nice. Great pick up and smooth shifting. Had it less than 2 weeks and the transmission started slipping. Only happens going up a hill and shifting to 3rd gear. Have to totally take foot off gas, let the engine slow down and it will change. Checked the trans fluid, it was fine, nice red color, not burnt/black.

Called 2 local trans shops and they said nothing to worry about unless it doesn't actually shift. Seems weird to me. Any ideas? Been doing it ever since. Doesn't "use" tranny fluid, I keep checking it.
