Just got a 2008 pathfinder, a lot of times the transmission will not shift I to 5th gear, unless I put it into manual mode and shift it there. Only problem there is 9 times out of 10 the manual mode does not work, when you push the shifter over to manual mode the D on the dash just stays there and no gear number shows up. Last night when I stopped at a light the transmission did not down shift and the pathfinder tried to start off in forth.
I have checked the tranny fluid and it is pink, radiator fluid appears fine.
Not sure were to go from here, any help would be great
