What are the differences of Clutch drag and clutch slip?

Clutch drag occurs when the clutch fails to fully disengage, causing the engine to continue to transmit power to the transmission even when the pedal is depressed. This can lead to difficulty in shifting gears and increased wear on the clutch components. In contrast, clutch slip happens when the clutch does not fully engage, resulting in a loss of power transfer from the engine to the wheels, often accompanied by a higher engine RPM without a corresponding increase in vehicle speed. Both issues can negatively affect vehicle performance and require attention.
