Automatic? Old school maintenance has always been the 30K timeframe, for automatic transmission fluid. Even with full synthetics, the automatic transmission fluid gets hot and it's additives get cooked. I do a full flush at 30K, pluss the pan drop and filter change.
Mu 2011 Owners maual states the autmatic transmission does not need service unto well over the 100K mark. This to me is just too much mileage to put on a transmission's fluid.
It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.
