Tranny linkage adjustment

Ok I checked all the linkages and they are properly adjusted and Im still having the same problem and its really starting to get old and starting to upset me to say the least!
2nd gear grinds coming from 1st and I have to slam it and I shouldnt have to do this and If I wind up 1st gear pretty high it will go in, but then Im still worried when I begin to let out on the clutch to possibly hear it grind. So Im asking you guys for help on what the problem could be? It also wont go into 2nd when downshifting as well. I have tried combo for it to just drop in.

Could it be the syncro? Please help
Thanks
