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.

1998 Pontiac Bonneville Owner Comments

problem #1

Mar 012004

Bonneville 6-cyl

  • Automatic transmission
  • 110,000 miles


Transaxle: After starting cold engine and driving 20-30 miles transmission starts shifting hard into 2nd, 3rd, and 4th gear. Does not shift hard when lock-up converter engages. Took it to Pontiac dealer and was told it was the pcs (pressure control solenoid) and it was going to be $700 to repair. Called several transmission shops and they said it could be the pcs or the valve body and most all 4T60 and 4T65-E transaxles have this problem"? if there are so many problems, why doesn't GM do something to at least cut the cost of repairs?"
