Yeah I figured. Good as brand new.

Hey, I bought my MacBook Pro refurbished from Apple, saved money and you wouldn’t know the difference.

 

This is an issue with all mechatronic transmissions, not just the 991 PDK built by ZF. Three separate issues:

1. Porsche programs the PDK to shift often in order to meet consumption and enviro standards. If you drive in traffic, it shifts unnecessarily often. Shifts generate heat. Heat degrades components.
2. Mechatronics and 911s are designed to be driven like sports cars, not automatic Toyota Corollas. If you putter in auto mode in stop-and-go traffic, it's going to run hot and eventually fail.
3. While Porsche claims these are sealed units that can't be repaired, indies do repair them and do so for a fraction of the cost.

Solution: Drive it like they're designed to be driven: sports cars. When in traffic, shift manually or in sport or sport+ to reduce the amount of shifts. Don't miss service intervals and if most of your driving is in stop-and-go traffic, consider changing the transmission fluid ahead of schedule. Lastly, should you have a failure, unless you're covered by warranty, take it to an indie specialist in Mechatronics and avoid the dealer like the plague.
