Correct...the output shaft will turn by hand,also may turn when the engine is running and in neutral,grab it and it will stop. When the truck is all together running in neutral it will not move as the weight of the truck is more than what the viscosity of the oil can push. It's all normal. Now, start your truck when its-35 and dump the clutch in neutral. The cold gear oil will either stall the engine or move the truck. I used to rev the engine up a bit when letting the clutch out,and let the engine run a bit. The oil would warm up on its own and then be good to drive and shift.
