Additional Notes

  • The Mitsubishi Montero Sport (USA / CAN) carries an automatic transmission fluid capacity of 9.7 liters across all listed 3.5 configurations, spanning the 1996-2004 model years.
  • A 9.7-liter figure represents a full system or overhaul fill, accounting for fluid held within the torque converter, valve body, and transmission case rather than a partial drain-and-fill service quantity.
  • Under normal use conditions, the specification calls for a fluid check at 15,000 miles or 12 months, with no fluid change interval listed for that condition.
  • Under severe use conditions, the same 15,000-mile or 12-month check interval applies, with the addition of a fluid change at 30,000 miles or 24 months.
  • The 3.5 two-wheel-drive and 3.5 AWD configurations share an identical 9.7-liter capacity, indicating no difference in transmission fluid volume between the two drivetrain variants.
  • The severe-use change interval of 30,000 miles or 24 months represents exactly double the check interval, placing a fluid change at every second scheduled inspection point.
