5 speed
is it still on the bench>????????
i rebuild many
1: the bearing in the front is bad.
2: the tranny is locked, bad shifter rail, detents
3: 4th gear is not a gear, it just locks themain shaft.
so if in 4th gear and input is jammed, that means
the cluster is jammed. if the cluster jams for any reason
it will be jammed in neutral. too, because the cluster always spins.
bottom counter shaft is called cluster. to old folks.
tell me , with the lid off tranny box.
did you test all gears, by moving the collars 1 by one.?????
each gear,? if not why not.????? never skip this step or fail big time.
then test all rail detents to make sure they all work(lid off)
and never allowing 2 gears selected at once (job1)????
then put in a new shifter sheet and try all gears on the garage floor,
all assembled!
then turn input by and and shift all gears on garage floor
i even use a huge drill motor to test tranny on floor, with tape on tip
of pilot shaft. and shift all gears,
this is all basics, , never just throw it together, do the tests.
as you go.
this one is close,
