I have an 01 Sportsman 500. Noticed recently in the cold weather that I am unable to shift the quad after it sits outside for extended periods. If I let it run for a few minutes or keep in inside heated garage I have no problem but issue returns once it sits and is cold. Is there a place that water could get in shift box? If so how do I get rid of it? Would a tranny fluid change fix it? I have not had the machine in any deep water or nor has it been wrecked/rolled so I am puzzled what is going on. Appreciate any help.
