904 shift pattern questions

yeah when i got the car he had the shift linkage hooked up to the throttle valve lever and the kickdown linkage was just hanging there. there was no shift lever on the trans at all so i got a B&M lever so that may be an issue as well. may need to find a stock lever.
I have not spent much time messing with it, when i went to push it the other day it would not move in N but rolled free in D. so i figured i would ask here before i spent any time under the car. i need to go over everything the kid did, as from what i am seeing who knows what he did.
