Transmission or Drivetrain Issue Preventing Movement
The vehicle is in gear but won't move when the engine is warm, indicating a likely transmission or drivetrain problem. This could be due to low transmission fluid, a faulty torque converter, or internal transmission failure. Brake or steering issues are less likely but possible if a caliper is seized or steering linkage is binding.
Diagnosis Details
Possible Causes
