It is exactly what my Magnd did!
And yes, Honda's grade logic works both uphill and down hill. My other car is a 01 Acura CL and it's got a traditional 5-speed auto with grade logic build in. It will hold a gear when going up hill, and will dowshift automatically when decending.
you could be right. The end result is that the Nissan CVT does feel and work like it had a grade logic build in........and I like it!
