Release and fill plug is up, toward the bottom of the vehicle.
Yep, helped a friend do a TC fluid change on an F30 335xi. It was kind of a pain. The bolt for the support bracket is probably the most annoying part. FWIW he didn't reset anything with ISTA and the car was fine, but we also did the change around 60k miles before there was any indication of TC oil wear when scanning.
