I have a 08' ranger 700xp. I'm having problems with the speedometer saying your in reverse when your actually in forward or neutral. The guy I purchased it from said it started doing it after he pressure washed the machine. Ive replaced the Speedo head with a new one and I replaced the range selector on trans with a used one we assume was good. Its also affecting the 4x4 sometimes engaging like a posi rear end even when in single wheel drive. Has anyone else had anything similar?
