help with transmission issue

I recently posted about issues with my trans.after some good replies I replaced my detent balls and springs and everything seemed to work fine.
This past weekend while on a ride my trans would hang in high gear.I can loosen the bolt that is against the detent spring (shift lever side)move shifter and tighten bolt and all works well,,low,reverse and neutral shifting until iI run a little in high gear and it will once again hang.
Also the inner detent doesn’t do anything when installed.so I left in out.
Any ideas what I’m looking at,,bent shift lever,worn out detent plate?
Machine only has 1500 miles.
