Additional Notes

  • The Jeep Gladiator JT transfer case fluid capacity appears in two distinct values across both the 3.0 Diesel and 3.6 engine configurations: 1.6 liters and 1.76 liters. The difference between the two figures reflects the existence of more than one transfer case unit fitted to the Gladiator across the model range, each with a separate fill volume.
  • For the 3.0 Diesel, the normal use condition ties a fluid check interval to 30,000 miles or 36 months, regardless of whether the transfer case holds 1.6 or 1.76 liters. A check interval, as opposed to a change interval, means the fluid level and condition are inspected rather than replaced at that mileage or time mark.
  • Under severe use conditions, the 3.0 Diesel transfer case fluid change interval is set at 120,000 miles or 72 months for both the 1.6-liter and 1.76-liter capacities. Severe use typically encompasses conditions such as frequent off-road driving, towing near maximum capacity, or operation in extreme temperatures.
  • The 3.6-liter engine configuration carries the same two transfer case fluid capacities of 1.6 liters and 1.76 liters, and the same normal use check interval of 30,000 miles or 36 months as the 3.0 Diesel.
  • A notable difference exists between the two engine variants in the severe use change interval. The 3.6 severe use interval is 60,000 miles or 72 months, which is half the mileage threshold specified for the 3.0 Diesel under the same severe use condition, while the time limit of 72 months remains identical across both engines.
