People are going to hate me for this. But how much can we attribute this new 6 speed transmission does not work to drivers not being familiar with it? I have drove and owned a couple of vehicles with 6 speed autos that where had shifting "surges" this only happened the first 3-5 days of driving the vehicle after that I no longer had the same issues. Do you remember the outcry when 4 speed autos became normal a lot of the same complaints where made then? I am not saying there is not a problem with the OP's transmission but in general do not handle change very well at all.
