These balls pop into a groove in the rail giving it the detent effect. Often one of these springs are broken & the shifter will move easily with out any resistance from the detent.
If all that makes sense you are good.

Yes I understand that and thank you. but it ended up not being the tower but the collar in the trans is stuck
