E46 323ci Steptronic question, Fluid coming out of transmission Breather, HELP!

I have a 2000 323ci 153k with an steptronic automatic Transmission GM built. I'm having a couple of issues with my tranny. First off, I live in Minnesota and it has been cold here and averaging 15 degree's out side. I'm not sure if the issues are because of cold. First Problem, when the car is cold and hadn't been started when I try to move the car the engine revs like its trying to move with the e-brake on, barely moves in forward or reverse, with that being said, the second issue happens, If you try moving it, fluid starts to come out of the breather hole on the top of the tranny. It leaves a decent puddle if you try to move it. Now if you start it up and let it warm for 10-15 Minutes without shifting it, it drives and shifts beautifully. I have done tranny fluid changes before this happened. I have done a fluid change after this happened and it drove fine twice and the problem is back again. It also started when it was below 25-30 degrees out. Has anyone had this problem or know whats wrong with it?
