That may or may not apply to the Nissan Versa. I don't know the specifics of its transmission but, for example, the recommendation isn't applicable/appropriate for the Honda 5-speed automatic in my VUE. It doesn't have a pan, filter, etc. The manufacturer-recommended procedure is a simple 3x drain and fill. I'm not sure the OP is asking about the procedure they should use or whether they're simply asking about the interval that they perform the Nissan-recommended procedure.
