Transmission Slipping or Torque Converter Failure
The engine revs freely but the car does not move, indicating a loss of power transfer from the engine to the wheels. This is most likely a transmission issue, such as slipping clutches, a failed torque converter, or low transmission fluid.
Diagnosis Details
Possible Causes
Low or contaminated automatic transmission fluid (ATF) causing hydraulic pressure loss and clutch slippage.
Failed torque converter (stator or lock-up clutch) preventing power transfer.
Internal transmission damage (worn clutches, broken bands, or valve body failure).
