Going down for 7 - 7.5% grades my toyota highlander. I drop it down 1 gear or maybe 2 out of 5 gears and it holds the speeds. I know the WV turnpike on some grades I have to drop it down 2, but its not an interstate highway, its a state toll road, which they are not governed by the interstate highway commision and can exceed the 7 - 7.5%.

Out here on the right cost we have only a few grades that are over 2-3 miles and they suck. I get dropped down to 55-60 MPH going up and as ShrimpBurrito said if I have to slow down behind a slow truck, I just about can not get back up to 55-60 MPH
