A little more info for you DIY guys:
Off camera I replaced the side filter and gasket and snap ring. This is part of the FCP Euro ultimate DCT service kit and straightforward to do.
Trans connector sleeve was leaking. There is more info in this post in case you need it
https://www.m3post.com/forums/showthread.php?t=1697657. Basically remove the T30 bolt, pull the connector back, remove the (red) seal and replace it with the new seal. Fwiw the new seal was black, some info online suggests that this is an updated part. Part number is 28607849555, runs about $22. Torque is 6 NM for the T30 bolt.
Mechatronic cover and gasket also leaking. BMW recommends replacing the cover which is about $300 (part number 28-60-8-064-572). I'm not sure if this was necessary but I did it anyway. The gasket is 28607842856. I also got all new bolts 28107842829 (x12). Torque for the bolts (M6) is 10 NM. A specific sequence must be followed according to TIS:
I reinstalled the trans. I had to lower the front subframe a bit and angle the engine toward the rear of the car in order to gain the necessary angle to align the bellhousing. This was definitely the hardest part. There are 5 aluminum torque to yield bolts that must be replaced. Part number 23001222893. There is also a specific torque sequencing for the bellhousing bolts:
M8x50 bolts 19 NM
M10 bolts 38 NM
M12x50 bolt 66 NM
Aluminum bolts M12 25 NM + 130 degrees
I still need to torque up the bellhousing, waiting for those Al bolts to come in. Later this week I will replace the oil pan and trans filter, and get the driveshaft bolted back up. All in all, it's been a challenging but fun project.
