Can a flywheel get stuck?

Likewise, can you drive with a bad flywheel?

A bad flywheel will likely be the reason for this because it will cause grinding of the plate and a lot more friction overall. If the gear keeps slipping when you change it, then it will certainly impact your driving ability and eventually damage your clutch.

Likewise, can a transmission lock up an engine? In a vehicle with an automatic transmission, the torque converter connects the power source to the load. Some of these devices are also equipped with a "lockup" mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.

In this way, how can you tell if your motor is locked up?

You can tell if your engine is locked by trying to turn the crankshaft with a breaker bar. If it turns, the engine isn't seized, and you should look for a different cause. If your engine has seized up while you're driving, there's nothing you can do about it short of an intensive engine repair or replacement.

Can you turn a flywheel by hand?

Insert the ignition key and turn the engine over. The ignition will activate the engine starter. Turn the flywheel with the ignition and starter until it is in place. The alternative way is to do it by hand.
