🔧 Types of Hybrid Gearbox Noise We Diagnose

Hybrid transmissions can produce several types of noise, each pointing to a different fault:

  • High‑pitched whining — usually bearing wear or PSD damage
  • Grinding noise — internal mechanical wear or metal contamination
  • Rumbling noise — MG1/MG2 motor generator bearing failure
  • Clunking or knocking — actuator or clutch issues (Hybrid DCT)
  • Whine under acceleration — input/output shaft bearing wear
  • Whine that changes with speed — planetary gearset wear

Correct diagnosis prevents major gearbox damage.

🚨 Symptoms That Require a Noise Specialist

If you notice any of the following, your hybrid gearbox needs immediate inspection:

  • Whining noise increasing with speed
  • Grinding or rumbling under load
  • Noise when accelerating or decelerating
  • Vibration through the drivetrain
  • Overheating gearbox
  • “Check Hybrid System” warning
  • Metal in gearbox oil
  • Loss of drive or intermittent drive

Hybrid gearbox noise rarely fixes itself — it gets worse.
