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.

Jetta GL 2.0L

  • Automatic transmission
  • 170,000 miles


my 2003 Volkswagen Jetta , overheated all that it needed was the temperature control valve was leaking . Now I need a transmission control module ? What does that have to do with the car overheating ? I took it to Kelly Volkswagen in Scranton Pa 1st I needed the main control module I purchased from a scrap yard , which was put in by another garage . then the dealership has to what they call flash the computer ? A series of turning the car on and off so the new computer can learn ? But I still don't know how my transmission has anything to do with my car overheating ? Also they want $1800.00 to put the module on the outside of the transmission ? Can anyone tell me where this control module is located ? Please Help

Thank you,
