BMW e90 problem with automatic transmission

I am owner of BMW 320D e90 automatic transmission . I have problem I guess with my transmission. When I ride approximately 80hm/h, and put of throttle pedal, I fell engine breaking and gears are downshifting regular and fuel consumption is 0. When speed comes to 40km/h it goes to lover gear but then fuel consumption goes up like on picture. I still dont touch throttle pedal at all. And I dont feel engine brake anymore like somebody push me from behind. Is this normal condition, and what problem may be? (sorry for my bad English I hope you understand what problem is)
