2011 TRX420FE – Rancher – Gear stuck in ‘R’

Hi. I am a new quad rider and love it so far. I bought a used Rancher as described in the subject. It has 940 miles on it and body was in good shape. Right after buying it, I painted it….picture attached!!! Anyways, i have only driven it 5 times and from time to time the up shift was not working while trying to shift higher. I kept pushing the button until it would finally shift. I kept riding thinking nothing of it. Finally, i stopped in 2nd……started to ride and it would not shift higher. I then stopped and found it would not shift higher, only lower, even when stopped. I ended up shifting into reverse and now i am stuck in reverse. Downshifting worked but upshiftiting did not. I ended up getting the the quad home (using a jack on rear), so that is positive. Now, i changed the angle sensor today and nothing changed. After changing the sensor, do i have to reset the computer? Not sure how if needed. The computer is giving me 2 long blinks and 2 short so code 22.

Can anyone help a new guy out? I took my quad to dealer and it was stuck there for 4 weeks before getting it returned and all i had done was a safety check and service. Id rather fix myself or ah least give it another try. Thanks.
