3 speed huge issue!

[d10s69c10]

alright first off i have searched the board but none of the other posts seemed to pin point my problem..

my whole tree is sloppy but i have worked around the issue in the past (3 years ago, trucks been parked) by jumping out and playing with linkage when truck was stuck in Second.

Now i am running into an issue all around, i have grinding as if the second gear Gear is riding on my main shaft the whole time .. in nuetral and even with clutch fully engaged when i come to a stop in first or reverse (still work) at 4mph sounds like a extra gear bouncing not meshed.

i have looked up and down and placed the linkage in every way i can think possible, but 90% of the time (10% it will stop till i put it in gear again) i crank up and let out on clutch to the same grinding.

seems like my outer link bar is only moving once down then back up but not any more.

so my question is?
a. it is done, get the auto
b. something broke inside?
c. spend the $$ on linkage (bushings) see if it works.
