Porsche Triptonic Tranny won't shift

Double check your transmission level. Your mechanic should be familiar with symptoms. But, it appears to be one of those things, that will require a visit to the shop. Make sure they describe what the problem is along with the remedy. -good luck-

I had the same problem with my 997 cabrio after checking the fuses to diagnose why I couldn't get certain functions of the car to work front and read lids opening no rear lights and not being able to bring down the top. This stemmed from a seal on the top letting water bypass when in heavy rain (BTW in the owners manual Porsche says this is normal.....Really!) To sum it up I found that there are several fuses that control the operation of the tiptotronic transmission. I would do some peeking around before you take it to the Porsche dealer. They would charge you for the oxygen you consume while in there if they could, Ex I had the "visit workshop light" come on and did some research on the forums to see if others had the same problem and what they did to remedy it. What I found were a whole slew of people saying that they were charged thousands upon thousands for things that did nothing to remedy the situation besides lightening the owners wallets. I fixed it myself at a red light by simply plugging in a $20 diagnostic tool and simply resetting the light not to have it return......For free
