  • Estimated Cost to Fix: $50 (PCV Valve) to $3000+ (Engine Rebuild/Replacement)
  • Recalls: None Found

6.0L L96 V8 Engine

• Catalytic Converter Failure
  • Description/Symptoms: Check engine light illuminated, often accompanied by diagnostic trouble codes (DTCs) related to catalytic converter efficiency (e.g., P0420). Potential symptoms include reduced engine performance, poor fuel economy, and a sulfurous smell.
  • Solution: Replacement of the faulty catalytic converter.
  • Estimated Cost to Fix: $800 - $1500+

Transmission

6L90 6-Speed Automatic Transmission (Paired with 6.0L V8)

• Harsh or Delayed Shifting
  • Description/Symptoms: Abrupt or jerky gear changes, hesitation when shifting between gears, or a noticeable delay when accelerating.
  • Solution: Could be caused by low transmission fluid, worn or damaged valve body, or internal wear of the transmission components. Start with a transmission fluid flush and filter replacement. If the problem persists, further diagnostics and repair of the valve body or a transmission rebuild may be required.
