Honda Ridgeline, YK1 (USA / CAN)

Automatic transmission fluid capacity & service interval

Honda Ridgeline, YK1 (USA / CAN) requires automatic transmission fluid with a capacity range of 3,1 to 8 liters. Service intervals occur every 30000 miles. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Honda Ridgeline YK1 automatic transaxle carries a dry fill capacity of 8 liters across all covered model years from 2006-2014, a figure that reflects the total fluid volume required when filling a completely drained or rebuilt unit, including the torque converter and all internal passages.
  • Routine service fill capacity is listed at 3.1 liters for all 2006-2014 configurations, which represents the amount of fluid displaced during a standard drain-and-refill procedure rather than a full overhaul, and the gap between the two values illustrates how much fluid remains trapped in the torque converter and valve body during a typical service.
  • For the 3.5 V6 in 2006-2008 under severe use conditions, a fixed change interval of 30,000 miles is specified alongside the 3.1-liter service fill capacity, indicating a time- and mileage-based maintenance schedule tied directly to demanding operating conditions such as frequent towing, stop-and-go driving, or extreme temperatures.
  • The 2006-2008 3.5 V6 also carries a flexible on-board maintenance system interval in addition to the severe-use schedule, meaning the vehicle's monitoring system can determine fluid change timing independently of a fixed mileage figure, with the same 3.1-liter service fill applying under that condition as well.
  • From 2009-2011 and again from 2012-2014, the 3.5 V6 retains only the flexible on-board maintenance system interval, with no fixed mileage interval listed for either period, while the 8-liter dry fill and 3.1-liter service fill capacities remain unchanged across both ranges.
  • The consistency of the 8-liter dry fill and 3.1-liter service fill figures across all three generation groupings — 2006-2008, 2009-2011, and 2012-2014 — indicates that the automatic transaxle unit's fluid holding capacity did not change across the covered production span of the first-generation Ridgeline YK1.
