Fml. yeah its the reinforcement metal plate. I guess there has to be a nut above. But I dont even know where to slide in a wrench to hold the nut above. this thing is just insane. At this point i think it might even be ATF fluid leaking as the resevior is really dirty and the hoses running from it. Also looks like fluid from there disappeared. I will find after the fan is out.
