Additional Notes

  • The INFINITI M Y50 transfer case fluid capacity is 1.3 liters across all listed AWD configurations, spanning both the M35 and M45 engine variants from 2005-2010. A consistent capacity figure like 1.3 liters across multiple model years typically reflects a service fill level rather than a full overhaul or dry-fill quantity.
  • Under normal use conditions, the transfer case fluid interval for the M35 AWD is specified as an inspection at 15,000 miles or 12 months, whichever comes first. A check interval rather than a change interval suggests the fluid is being evaluated for condition rather than replaced on a fixed schedule.
  • Under severe use conditions, the M35 AWD transfer case fluid is subject to a change at 30,000 miles or 24 months. The severe interval doubles both the mileage and time thresholds compared to the normal-use check interval, and it specifies an actual fluid change rather than an inspection.
  • The M45 AWD, available from 2008-2010, carries the same 1.3-liter transfer case fluid capacity as the M35 AWD. Despite the difference in engine displacement between the V6-powered M35 and the V8-powered M45, the transfer case fluid specifications remain identical.
  • The M45 AWD follows the same interval structure as the M35 AWD, with a normal-use check at 15,000 miles or 12 months and a severe-use change at 30,000 miles or 24 months. The alignment of intervals across both engine variants indicates a shared transfer case unit or at minimum a shared service schedule.
  • The M35 AWD transfer case specifications are divided into four separate year groupings: 2005-2006, 2007, 2008, and 2009-2010. Despite the segmented year groupings, the capacity and interval values remain unchanged at 1.3 liters, 15,000-mile checks under normal use, and 30,000-mile changes under severe use throughout the entire 2005-2010 span.
