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.

Car literally clunks into gear. Especially going from park to reverse, or vis versa. Other gears are not as bad.

Ok this problem with the transmission I guess is very common in the Impalas, I was lucky to have the opportunity to rack up almost 200k miles on mine before it happened but some people aren't that fortunate. The shaft from the transmission pump to the torque converter somehow pops a seal out which allows the shaft to start going oblong and eats the gears up, without the seal there the transmission fluid flows through heavier and builds up high pressure in the lines and makes the car slam into the next gear. So from what I was told I am just wandering how the hell does GM borrow so much damn money and still can't seem to fix a problem that has been brought to their attention I'm sure many of times.

Tranny clunks into gear randomly and has now also randomly caused the traction control lamp to illuminate. (Note, ABS lamp never came on so far). Garage flushed tranny and put in new filter, no improvement.
