Honda Ridgeline, YK2/YK3 (USA / CAN)

Additional Notes

• The Honda Ridgeline YK2/YK3 3.5 V6 AWD transfer case holds 0.43 liter as a service fill capacity across all listed configurations from 2016 onward, meaning the figure reflects the amount of fluid used during a routine drain-and-refill rather than a complete overhaul or dry-fill procedure.
• The 0.43-liter service fill figure remains consistent across both the 2016-2019 entries and the 2019 entries, with no variation in transfer case fluid capacity tied to model year changes within the listed data.
• Among the 2016-2019 configurations, two distinct use conditions appear: an alternative (acceptable) fluid designation and a flexible interval tied to an on-board maintenance system, both paired with the same 0.43-liter service fill capacity and no stated mileage or time interval.
• For the 2019 onward severe use condition, a specific change interval of 30,000 miles or 24 months is listed alongside the 0.43-liter service fill, making severe use the only configuration in the dataset that carries an explicit mileage and time-based service interval for the transfer case.
• The 2019 onward flexible use condition, governed by the on-board maintenance system, lists only the 0.43-liter service fill capacity without a fixed mileage or time interval, consistent with how on-board maintenance systems operate by calculating service needs based on driving conditions rather than fixed schedules.
