My '04 CayenneS Transmission


Recommended Posts

I want to share my story to help us, owners, understand about Cayenne.

The symptom began like this:

Everyday when first start the car - put it in Drive, hit the accelerator, the car won’t go after 1-2-3 seconds then the transmission engaged causing a big jerk. It’ll do that every time I stop at a stop sign or traffic light. After about 15 minutes of driving the problem gets better but not gone, it’ll do that unexpectedly. To solve the problem temporary, I used manual shifting.

Took it to the dealer. They replaced the Transmission Control Module. Before the day was over, they called and said a different fault code appeared, it’s a gear indicator sensor (or something similar to that) and that the sensor is inside the transmission. To replace this sensor, I need a new transmission (!?!?).

Somebone must have watched over me when I bought the car, I bought extended warranty because this is my first Porsche, don’t know anything about it.

The warranty Rep. came out and confirmed that the transmission is bad and approved for a replacement!

After a few days, I called the dealer to check for status, they said the transmission is replaced but still received a fault code and they thing that it’s the Transmission Control Module. They replaced the “more expensive version or the latest version” of the Control Module.

Well, I got my car back and it’s operating normal now, after spending 13 days in the dealer (between holidays & week ends).

he control module needs to be an exact match. Also you will not have an 04 transmission, when they changed mine they told me they were only using 05s or later. mine has been good for 70K miles since it was done
