All, I’ve done an exhaustive search both on this forum and google and I can’t find an answer to my problem. I have a 2001 non turbo C2 996 cabrio with a automatic/tiptronic trans. The transmission’s torque converter unlocks VERY easily. If I’m cruising at 70mph and I give it more than 5% throttle, it unlocks. Once it unlocks, I cannot get the torque converter to re-lock unless I completely let of the gas pedal. Needless to say, my gas mileage is suffering and it takes some effort to try and keep the torque converter locked while at speed. I do NOT have any DTC codes and there is no check engine light. Therefore, I assume this issue if likely mechanical and not electrical. My thoughts on the problem: Soft failure of the throttle position senor (integrated with the electronic throttle body) Bad TCC solenoid in the valve body Bad valve body (valves leaking by/not properly seating or diverting fluid) Bad Torque Converter Any comments of help would be appreciated.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
