Just did the fluid and filter on my 13 35i. In fact there are two plugs. 1 is next to the drive shaft (one I use) and the other one is on the rear passenger side of the transmission, hard to see (is right below the sealing sleeve) Link shows the plug on the rear. Yeah it’s for an e90 but same trans. (On the comments he says that the plug next to the driveshaft is slightly higher that the one on the rear)
