Tranny linkage adjustment

I have checked my linkage on my A833 and they are adjusted properly and it grinds going into 2nd gear and I have to slam it in gear and i know that is not good. It also doesnt go into 2nd downshifting either. Now I can wind up 1st gear and go into 2nd gear, and Im getting frustrated and upset that its doing this.
Could this be a synchro thats damaged? Also reverse grinds badly after I make a complete stop and try to back up it sounds horrible
Please help
