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.

2003 GMC Yukon Owner Comments

problem #1

Jun 152012

Yukon SLT 4.8L

  • Automatic transmission
  • 117,000 miles

This vehicle only has 117,000 miles on it. I came to a complete stop, put the vehicle in reverse and heard a loud bang, and a whining noise. Vehicle would not move backward. So I put it in drive and suddenly it jerk into gear. As I went through the parking lot you can hear a loud whining noise coming from the tranny sounding like I had a cat caught up in the gears. When I had a chance to limp it to the mechanic it would shift pass 2nd gear. So I had to replace the tranny. Almost $2000 later for a problem that I was told that is common for this transmission. It seems like GM would have know this and fixed this problem. I was told it was the shell gear had broken. And by simply making it a little thicker this could have prevented this problem.
