Hard starting cranks won't start. on 2001 Ford F-250 Super Duty

I really have 2 questions, first, I keep it plugged in during the cold weather, it cranks good, won't start, batteries check good. Finally a little jump and it starts. 2nd on a small or medium incline automatic transmission doesn't engage fine and smooth all other times,

YOUR BATTERIES MIGHT BE GOING BAD INTERNALLY AND SULFATING. ON YOUR TRANS ISSUE HOW IS THE FLUID LEVEL AND COLOR. YOU MIGHT BE HAVING A CONVERTER DRAIN ISSUE. CONVERTER MIGHT BE LETTING FLUID DRAIN OUT AND THIS TAKES A FEW SECONDS TO REFILL AFTER START UP.
