Mercury Mariner

Manual transmission fluid capacity & service interval

Mercury Mariner manual transmission fluid capacity ranges from 2,2 to 2,7 liters. Service intervals include checks every 15000 km or 12 months and changes every 90000 km or 72 months. The data covers 4 configurations.

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

Additional Notes

  • The Mercury Mariner manual transaxle specifications list two distinct fluid capacities across both the 2.3 16V and 3.0 V6 engines: 2.2 liters and 2.7 liters. The lower figure typically corresponds to a drain-and-fill service, while the higher figure reflects a fuller overhaul or dry-fill capacity where the housing is completely emptied.
  • Both capacity values, 2.2 liters and 2.7 liters, appear under normal use conditions for the 2005-2008 model years, meaning neither figure is tied to a severe-duty or special-case scenario.
  • The 2.3 16V and 3.0 V6 engines share identical capacity values of 2.2 liters and 2.7 liters for the manual transaxle, indicating no engine-driven difference in fluid volume requirements between the four-cylinder and six-cylinder configurations.
  • The fluid check interval for all listed configurations is 15,000 km or 12 months, whichever comes first, under normal use. A 12-month time-based threshold means calendar time alone can trigger a check even when mileage accumulation is low.
  • The fluid change interval is set at 90,000 km or 72 months across all four rows. A 72-month ceiling means a six-year time limit applies regardless of whether the distance threshold has been reached.
  • The ratio of check interval to change interval is 1:6 by distance and 1:6 by time, meaning six check cycles are expected to occur before a fluid change is due under normal use conditions.
