The wifes always did. She had an 10. It shifted rough and oddly when cold from when we bought it ae 48k clear up to 170k when we offed it. Never had any issue though.Yeah, my brother got a '11 I believe and has done some looking into them, apparently they're a bear to remove...
Depending on what it's doing I would just drain the 4 quarts you can externally and refill, that fixed his odd shift problem... if it's slippin that's a whole different thing... apparently they do hold first for a long time when they're cold...
