Additional Notes

  • The Jeep Grand Cherokee / Grand Cherokee L (WL) transfer case holds 1 liter of fluid across all listed configurations, which is a relatively modest capacity consistent with modern compact transfer case designs used in passenger-oriented AWD systems.
  • A 1-liter transfer case fill volume is a service fill figure, meaning the amount required during a routine fluid change rather than a full overhaul or dry-fill scenario where additional passages and components would need to be accounted for.
  • Under normal use conditions, the transfer case fluid check interval is set at 30,000 miles or 36 months for all four configurations listed, whichever comes first.
  • The fluid change interval under normal use conditions is 60,000 miles or 72 months, which is double the check interval, indicating a structured two-stage maintenance schedule where inspection precedes replacement.
  • The 3.6 V6 AWD and 3.6 V6 AWD FlexFuel variants, both starting from 2021, share identical transfer case capacity and service intervals despite the FlexFuel designation introducing a different fuel system, suggesting the transfer case hardware is common between the two.
  • The 5.7 V8 AWD configuration, despite carrying a significantly larger and more powerful engine, carries the same 1-liter transfer case capacity and the same 30,000-mile check and 60,000-mile change intervals as the V6 variants.
  • The 2.0 4xE PHEV configuration starts from 2022, one model year later than the V6 and V8 AWD variants, yet shares the same transfer case fluid capacity of 1 liter and the same check and change intervals under normal use conditions.
