S80 Automatic Transmission Problem
Summary of the thread
A 2008 Volvo S80 diesel is experiencing issues where the engine won't start in park, the check engine light is on, and the gearbox slips. An error code suggests a defective transmission control module, which may affect the park brake engagement and gear selection logic. The problem is similar to a past issue with a Renault, where a faulty sensor on the gear stick prevented starting. The suggested solution is to consult a qualified workshop to address the transmission control module issue.

Yes, there's a specific code indicating a fault within the transmission control module, potentially affecting the park brake engagement and overall gear selection logic. Could you elaborate on the specific sensor that failed in your Renault, and if that failure also prevented starting the car?

Yeah, the Renault thing totally prevented the car from starting sometimes. It was a sensor on the gear stick itself that tells the car what position its in. I'm no mechanic, but from what you're saying, with your Volvo needing a whole new control module, it sounds like a workshop job to me. Better get it checked before you cause any more damage.

Hey, that sounds rough. I had something similar happen with my old Renault a few years back. Engine wouldn't start sometimes, and the gear shifts felt clunky. The check engine light was always on too. It turned out to be some sensor related to the gear shifter, messing everything up. Is the Volvo showing any specific error codes?
