Transmission or Drivetrain Failure
The vehicle won't move when the engine is cold, indicating a possible transmission issue, torque converter problem, or drivetrain component failure. This requires immediate diagnosis to prevent further damage.
Diagnosis Details
Possible Causes
Low or contaminated automatic transmission fluid (ATF) causing hydraulic pressure loss, especially when cold and fluid is thick.
Torque converter failure or stator clutch malfunction preventing power transfer from engine to transmission.
Broken axle shaft, CV joint, or differential failure, particularly if the engine revs but the vehicle doesn't move.
