Transmission Slipping or Clutch Failure
The engine revs freely but the vehicle does not accelerate properly, indicating a loss of power transfer from the engine to the wheels. This is most commonly due to a slipping transmission (automatic) or a worn clutch (manual), but can also be caused by a failed torque converter or low transmission fluid.
