Additional Notes

  • The Jeep Comanche MJ (EU) automatic transmission fluid capacity differs between the two available engine configurations, with the 2.5i requiring 6.6 liters and the 4.0i requiring 8 liters.
  • The 1.4-liter difference in fluid capacity between the 2.5i and 4.0i reflects the larger transmission unit paired with the bigger inline-six engine, which typically involves a greater number of internal clutch packs and a larger torque converter.
  • Both engine variants share an identical fluid check interval of 12,000 km or 12 months, whichever comes first, under normal use conditions.
  • The change interval for automatic transmission fluid across both the 2.5i and 4.0i is set at 48,000 km or 24 months under normal use, meaning the fluid is changed once for every four check cycles.
  • The 8-liter capacity specified for the 4.0i under normal use conditions represents a full service fill, which in automatic transmissions typically accounts for fluid retained in the torque converter, valve body, and cooler lines in addition to the pan.
  • Both configurations cover the full 1987-1992 model year span without variation in capacity or interval figures across those years.
