Additional Notes

  • The Jeep Cherokee/Liberty KK (3.7 V6 AWD) transfer case fluid capacity is listed at either 1.8 or 1.9 liters across all configurations, reflecting a small but consistent variation that corresponds to different transfer case units fitted to the same engine and drivetrain combination.
  • For the 2007-2010 model years, the normal use condition calls for a fluid check at 30,000 miles or 30 months, whichever comes first, rather than a full fluid change, meaning the interval is an inspection threshold rather than a mandatory replacement point.
  • Under severe use conditions for the 2007-2010 generation, a fluid change is specified at 60,000 miles or 60 months, doubling the distance and time threshold compared to the normal-use check interval for the same period.
  • The 2010-2012 generation carries a revised normal-use check interval of 32,000 miles or 24 months, which shortens the time-based threshold from 30 months to 24 months relative to the 2007-2010 specification, while extending the mileage threshold slightly from 30,000 to 32,000 miles.
  • Under severe use for the 2010-2012 generation, the change interval is set at 64,000 miles or 48 months, again doubling the normal-use mileage and time figures, consistent with the same doubling pattern seen in the earlier generation's severe-use specification.
  • Both the 1.8-liter and 1.9-liter capacity variants share identical service intervals within each generation and use condition, meaning the capacity difference alone does not alter when a check or change is due.
