Couple questions
- With the Pentosin fluid being super expensive now, has anyone tried liquimoly 8100 ? I have 7 liters and will be trying it.
- Does a transmission swap require any electrical / flashing ? Will I have to get winKFP working again to flash it with the VIN?
- anyone know offhand if there's a good DIY guide to removing the DCT or a general list of things to look for?
- Should I replace the top mechatronic sleeve as a whole or will a new O-ring suffice? Those can leak but less often and less severely.

Gutsy...I wouldn't be inclined to trust a $1000 unit...
Absolutely replace all external seals including mechatronics seal. You'll kick yourself if you don't and have to pull the trans to later replace it.
LM 8100 is fine- it carries the BMW certification. Same as Motul DCTF, Pentosin, Redline, Shell...
There are differences in early DCT and late DCT units with electrical and grounding schematics etc. Best to find one from a similar year, or at a minimum match Pre/post LCI.
DCT swap absolutely requires specialized software actions and is not a simple WinKFP session for someone loading it up for the first time. Recommend contracting a specialist for this operation.
