Does anyone know the model number/designation of the Tiptronic included with a 2008 997 Turbo? I heard it may be a ZF unit?

I've found a car that has upgraded clutch packs/TQ converter and valves curious to do some research on it. I understand that if you put the tiptronic into "sport" mode with the sport chrono package and if the valve's have had some work, it can actually be a pretty nice shifting car?

 

The only codes i know are that its a mercedes box 722.6

Other codes on the box are 722.657, A722 270 20 00, A9750 150.

 

Thanks. Found a bunch of info looking at that, doing some research.
