My new to me 2005 Cayenne S with 100k just had the check engine light come on. It drives fine but the Code p0841 is for a transmission  fluid pressure  sensor.

I took it to a Porsche indy shop and the called me saying it needs a transmission valve body, 2 harnesses ,fluid , filter and gasket for a little under $5000!

Does this sound right?


The vehicle drives fine no  noises , clunking  chattering and shifts smoothly.



I just bought the car in March for $9000 k

Fault code 1236 (P0841) Shiftlock solenoid


Troubleshooting in the Porsche service manual says to replace just that solenoid.

It might be a good thing to try another shop.
