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.

2000 Pontiac Bonneville Owner Comments

problem #2

Feb 172007

Bonneville SLE 3.8L

  • Automatic transmission
  • 95,000 miles


Transmission started doing rough shifting, felt like was running over a speed bump. I noticed it went away after I had stopped the car and turned off engine. I had it diagnosed at transmission repair shop and they said many GM cars with same transmission have same problem. They said it was solenoid problem but would cost almost as much as doing complete transmission repair ( $1200 to $1800) since the solenoid was inside the transmission box. I decided to wait until I needed a complete transmission repair to have it fixed.

Bonneville SE 3.8L V6

  • Automatic transmission
  • 39,000 miles

rough shifting, especially when hot...This transmission was rebuilt by the dealer and went out again in the same manner about 30,000 miles later. It required a new transmission the second time (@74,000 miles). On the other hand, my 1989 Bonneville has 167,000 with the original transmission and engine running great.
