Eh, my post dissapeared.
Ya got TWO cables, one f & b, one l & r.
If l-r dies, trans reactes there to center, so you just get 3 & 4.
If f & b dies, you get no gears.
Your video doesn't show both cables, but if the other end doesn't move: cable prob, if it does: trans problem, or if it tries to but can't: somethin blockin it
