My 2015 outdoorsman 107K mi has been having problems with engaging the gears when I turn the shift knob. The light will flash on the selected gear knob but all not engage. I put it back in park and than try gear and still does not engage. I turn the truck off wait a minute and start it again and it works. I thought it may be low on transmission fluid so I checked it, but it was not. I had the transmission fluid and pan changed at 100K. Am I heading for big problem!
