I just answered the OP because not many had answered yet and wanted to keep it on top for him. Never heard of the Winter Shifter and looked them up to see what the op was referring to. I have very little experience with an Auto shifter except when I drag race my friends reverse manual auto on the Col. 10 second A12 Super Bee and find it is such a smooth pass with 4500 stall and 488s. Only thing you have to worry about is over shifting it from 1st to 3rd.
