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.

I had the tranny flushed and that has helped. I still get a hesitation as it shifts from first to second.

Transmission slipping. Started in 2005 but was barely noticeable when I purchased the vehicle. Has been progressing to the point when I think it will die at any time. I talked with a transmission mechanic and he says the transmission will need to be rebuilt or replaced. Rebuilt is about $2,600. Not sure if I am going to do this as the van is already 10 years old.

There a nice looking van but GM has just had so many problems with them. Sometimes while taking off your car will sit in place and shake while your transmission tries to catch. When it finally does it makes a big thud and jolts forward. awful feeling, I know lots of people who have this problem
