Pretty sweet stuff. If you have the DSG trans cracked open (or when you do), could you post pics of what it looks like in there and how involved it is to install the wavetrack and new clutchpacks? I'm curious as to why the labor is so intense on DSG.
Internally they are very similar to the the 6spd manual, just more work to get to the internals and more parts/seals needed then a manual once they are opened.
Like Tom said they are very similar (DSG-6MT), it basically looks like a manual with hydraulics and some sensors.
Cost is more labor, more to take apart and its also heavier. You also need to replace some parts when opening when you don't do with a manual.
