Rancher AT shifting problem

Ive got a 2009 Rancher FPA IRS and im having a problem with it not want to shift from Neutral to first or from Neutral to Drive. It doesn't do it all the time but it does seem to be happening more often and it does it cold and when its hot. Ive also noticed that in auto it doesn't want to shift up if your holding full throttle, you have to back off to let it shift. Its got 180 hours and 1700 miles on it. I changed the shift angle sensor hoping that was the problem but no change and i checked the shift motor and gear assembly and its all clean and seems to be working properly. Has anyone else had any of these issues with a DCT trans or have any idea what my problem is, any input is appreciated.
