12	Remove seal (arrow A) from torque converter housing (1).
	Clean
13	Clean sealing surfaces on torque converter housing (1) and transmission housing (3).
14	Clean threads for screws (14) in transmission housing (3).
	Install
15	Attach new seal (arrow A) to torque converter housing (1).
16	Align disks of clutch pack BR (12) and multidisk brake B2 (13) in transmission housing (3).
17	Place transmission housing (3) onto torque converter housing (1).	 Place transmission housing (3) carefully. Otherwise, the disks of clutch pack BR (12) and multidisk brake B2 (13) will break off.
18	Mount output flange (8).
