Dean, I suspect that you have some moisture in the line that has frozen OR the air line going into the shift unit on the side of the transmission has deteriorated and blown some of its lining into the small holes that allow air to move the piston. Lets hope it is the former. Might try putting a heater blowing on the unit (don't get it too close) to see if that helps first.
