The car starts normally, but when I shift into Drive or Reverse, the car starts making a hard knocking sound, and the engine starts moving all over.
It sounds like you have a broken engine or transmission mount, causing your engine to move. You could also have an engine misfire. An inspection of your engine’s knocking sound from a qualified technician, such as one from YourMechanic, can help you determine the cause, and fix your issue.
