Any position ?or three out of five?
If you find one position,(like fourth for instance), then;what @mcodecuda said.
it happens all the time with units in storage. Just stick a screwdriver between the brass and the clutch teeth and give it a lil twist to make sure it's loose. If all 4 are already loose, IDK.
Since it spins at 1:1; it would have to be locked input to output, and I've never seen that...
If I had to guess I'd guess the output has slipped forward. Altho I see no evidence of that.
More likely is that the Fourth-Gear brass is jammed into the brake because the struts are out of sync; I've seen rooky assemblers make that mistake.
