Additional Notes

  • The Honda Ridgeline YK1 3.5 V6 rear differential carries a dry fill capacity of 2.85 liters across all model years from 2006-2014, a figure that applies when the unit is completely empty, such as after a full overhaul or component replacement.
  • The service fill capacity of 2.64 liters is consistently specified for the same 2006-2014 range, reflecting the smaller volume needed when some residual fluid remains in the differential housing during a routine drain-and-refill service.
  • The 0.21-liter difference between the dry fill and service fill values across all three generation groups (2006-2008, 2009-2011, and 2012-2014) indicates a consistent housing design where residual fluid is retained even after draining.
  • Under severe use conditions, a 15,000 km rear differential fluid change interval is specified for all three generation groups, with no variation in that interval across the 2006-2014 production span.
  • A separate severe-use interval of 7,500 miles is listed specifically as a first-change-only requirement for all three generation groups, meaning the initial fluid change occurs at a shorter distance before the standard 15,000 km interval takes over.
  • The first-change-only interval of 7,500 miles and the recurring severe-use interval of 15,000 km are expressed in different units of measurement within the same specifications, which reflects a mixed-unit approach rather than a direct unit conversion between the two values.
  • For all model years from 2006-2014, a flexible interval tied to the on-board maintenance system is also listed, under which no fixed change distance is specified and fluid change timing is instead determined by the vehicle's own monitoring logic.
