Additional Notes

  • The Jeep Gladiator JT with the 3.6-liter engine carries a manual transmission fluid capacity of 2.25 liters, noted as a dry fill figure, meaning the measurement reflects a fully drained and refilled unit rather than a partial top-up.
  • A dry fill capacity is typically recorded after a complete transmission overhaul or replacement, so the 2.25-liter figure represents the total system volume rather than a routine service quantity.
  • Under normal use conditions, no fluid change interval is specified for the manual transmission, while severe use conditions carry a defined service interval of 30,000 miles or 36 months, whichever comes first.
  • The capacity value of 2.25 liters remains consistent across both normal and severe use conditions, indicating the fill volume does not vary based on operating environment.
  • The 30,000-mile or 36-month interval tied to severe use reflects a shortened service cycle compared to normal conditions, which is standard practice when a transmission operates under higher stress, such as frequent towing, off-road use, or extreme temperatures.
