You might try greasing up the internal shifter mechanism of the shifter box. My C5 had very little lubricant on the shaft and was pretty hard to shift. After lubrication it shifted so much better. I was going to do the anti venom mod but I felt it's not necessary. I have the washers so I still might do it. The other thing is that if it's reved up a bit, like to 2500 rpm it shifts much smoother..
as well as what WICKEDFRC states above.First pull the lower box out and inspect it. Check your bushings and play in the box itself. If lingage is firm (not a lot of play when you shake the box) grease it up and give that a try. If the box is slapping around go to plan B...new lower box.
I was having shift accuracy issues a few years back with my B&M Ripper. Pulled the lower box and it had so much play in it. The linkage was slopping around when I shook the box. Plus the bushings were pretty shot.
Swapped the lower box for a "low mile" used C6 lower box bought off ebay for $25 (no slopping or slapping around when I shook the box) and shifts are much more true again. No Anti Venom mod required.
