Hard to up shift

[evil_hero]

Hey all.
Drove to work today in the AM, not a problem. Went to head home today, stopped at a red light and had to readjust my backpack so I had to shift to N, I tried and tried, and finally and had push my foot way up, so i could get enough leverage to get it into N. After that, it was crazy hard to shift up, shifting down is fine. What I ended up doing was instead of shifting up with my toe i had to reach my foot over and kick it back with my heel. Few miles of that, then it started shifting easy again.....then few more miles down the road, extremely hard again.

Any ideas?

Thanks
