CAR SELECTS GEAR
BUT WON'T MOVE.
You shift into Drive or 1st gear, the engine revs normally when you press the accelerator, but the car remains stationary as if it is stuck in Neutral. Here is how to tell whether the problem is a broken driveshaft, a failed clutch, or an internal transmission issue.
What Does Total Loss of Drive Feel Like?
- Zero forward or reverse movement: The speedometer might even register speed when you rev the engine, but the car does not move at all.
- Whirring or spinning sound underneath: A faint spinning or clicking sound can be heard from the engine bay or wheels when throttle is applied.
- Car rolls freely in Park: On an automatic, the car may roll even when placed in 'P' if a driveshaft or CV joint has snapped.
Can I Keep Driving?
Evaluating whether your vehicle is safe to drive or requires immediate recovery:
What Could Cause It? (Symptom ≠ Diagnosis)
1. Snapped Driveshaft or CV Joint
⚠
External fault: If a driveshaft snaps or a CV joint pops out, the open differential sends all engine power to the broken spinning shaft, leaving zero drive to the road wheels.
2. Complete Fluid Loss (Automatic)
⚠
Hydraulic fault: If an oil cooler line splits or a sump pan gasket fails, the transmission oil pump cannot build pressure, preventing all clutches from engaging.
3. Stripped Splines or Burnt Clutch
⚠
Mechanical fault: A completely stripped clutch hub, sheared torque converter drive plate, or differential pinion failure stops rotational power transfer.
How We Diagnose and Resolve Total Loss of Drive
How We Diagnose and Resolve Total Loss of Drive
Diagnostic Step-by-Step
- Visual ramp inspection of both front and rear driveshafts, CV boots, and hub splines
- Transmission fluid level and line pressure measurement
- Electronic scan for TCM communication and hydraulic pump pressure codes
- Inspection of torque converter flexplate bolts and input shaft splines
Potential Repair Pathways
- Driveshaft or CV Joint Replacement (external repair)
- Clutch Kit & Hub Replacement (for manual cars)
- Torque Converter & Flexplate Renewal
- Complete Reconditioned Transmission Unit (if differential or mainshaft is stripped)
