25 Code is no big deal. It goes off at one point or another on all these machines. My dealer called it a dummy code. It is listed in the Polaris Dealer Service Manual as a transmission error code. It can get tripped if you shift too quickly or having the rpms up when you shift. It will clear on its own or you can disconnect your battery for a minute or so to reset. As long as it shifts correctly and goes into P.R.N.L.H. and they show up on the indicator you should be good, otherwise it may need a minor adjustment.
