Yes, you can turn the input shaft by hand when the transmission is out of the car, assuming there are no internal obstructions or damage. However, it may require some effort, depending on the transmission type and its condition. It's important to ensure that the transmission is in neutral to facilitate easier turning of the shaft.
with the combustion of the gasoline in the cylinders, the pistons are forced up and down, turning the crank shaft which then activates the transmission which sends energy to the drive shaft which in turn spins the wheels.
Manual transmission that is in gear-YES
No, it's bolted to the end of the crank which pistons/rods attached to.
Crank shaft sensor need replaced or cam shaft sensor
