I live in alaska and my b4000(ranger) is having clutch problems. the other morning it was about -30f and I started the truck. when it had warmed up for about 20 minutes i went to leave but half of the clutch throw was free play. the bottom half was not enough to allow me to shift into gear with the truck running. I could shift into gear with the truck turned off, but as soon as I started the truck with it in gear it would start to creep with the clutch all the way to the floor. I checked my master cylinder reservoir and it was low so i added fluid to the correct level but the clutch problem still wasn't resolved
