Transmission issues

Sup guys, so i ran into this issue a few days back. Now my reverse gear does not always click into gear when I am reversing sometimes. This happened a few days ago so what i do is take it back to nuetral and try to put it in reverse. I did this on several occasions, got kinda mad and yanked it hard in there lol. Well it went into reverse alright but now i have some issues goin on with 2nd, 4th and reverse gears. They feel very mushy, like they dont have that crisp gear change in them anymore. It does it now once in a while but things kinda got worse today when second gear doesnt even wanna engage!! 4th and reverse are fine. 1st, 3rd and 5th have no issues and have that crisp gear change. What do you think has happened with the lower gears?
