lately my stock besides bolt ons and LSD has been locking me out of 2,4, R. It goes but not all the way in. sometimes it cant move left or right in neutral, only to 3 gear when that happens. when I play with it it works fine then on and off while im driving.

 

95 gsr

 

i need help on what it could be

 

Do you have an aftermarket exhaust? Mine did almost the same exact thing and it turned out to be the shift linkage was getting caught on the exhaust hangers that are right by it. Check and make sure its not that.
