i went out to the garage last night to sit on my 2000 xplorer 250 and the shifter was froze up solid. temp was in the high teens. this is the first winter ive had this machine. i started her up and warmed for about 5-10 mins and was able to get into forward but didnt want to mess around more and break something. my question is is this common and/or what is the remidy? thanks guys.
