Additional Notes
- Both the 2.5i and 4.0i engine variants of the Jeep Comanche MJ (EU) share an identical manual transmission fluid capacity of 3.5 liters, indicating the same gearbox unit was paired with both engines across the 1987-1992 production span.
- A 3.5-liter fluid capacity is consistent with a service fill figure, meaning the quantity required when refilling a drained but otherwise intact transmission, rather than a full overhaul fill that would account for additional fluid retained in ancillary components.
- The check interval for manual transmission fluid on both configurations is set at 12,000 km or 12 months, whichever comes first under normal use conditions, reflecting a once-per-year inspection cycle tied to either distance or time.
- The change interval under normal use conditions is specified at 60,000 km or 30 months, which works out to a fluid replacement roughly every two and a half years when the time-based threshold is applied.
- The ratio between the check interval and the change interval is exactly 1:5 by distance, meaning five check cycles are completed for every one full fluid change cycle across both the 2.5i and 4.0i variants.
- The specifications apply exclusively under normal use conditions for both engine configurations, with no separate severe-use interval listed for either variant in the 1987-1992 range.
