-
Transmission Fluid:
- Automatic (8HP75): This is a “sealed for life” unit by some manufacturers’ standards, but we at FatBoysOffroad recommend considering a fluid and filter change around 60,000-80,000 miles, especially with heavy use or towing. This requires specialized tools and fluid, so it’s often a job for a professional.
- Manual (D478): Check fluid levels regularly. Change interval is typically longer, but check your owner’s manual. Use the specified Mopar fluid.
-
Differential Fluids:
- Frequency: Critical for off-roaders! Check every 30,000 miles or more frequently after water crossings. Change every 60,000 miles or sooner if you frequently submerge your axles.
- Type: Use API GL-5 rated gear oil of the correct weight (e.g., 75W-90 or 75W-140, depending on axle type and use). Don’t forget friction modifier if you have a limited-slip differential.
- DIY: Requires a 1/2-inch drive ratchet for drain and fill plugs, a fluid pump, and a drain pan. Consider upgrading to differential covers with drain plugs for easier changes.
-
Coolant System:
- Check Level: Before every long trip, ensure the coolant reservoir is between MIN and MAX lines when cold.
- Condition: Look for discoloration or debris in the coolant. Flush and refill according to your owner’s manual, typically every 5 years or 100,000 miles. Use only Mopar OAT (Organic Acid Technology) coolant. Mixing types can cause serious damage.
Suspension, Steering, and Brakes: Keeping Your Gladiator Tracking True
These components are vital for safety and handling, particularly off-road. Regular checks contribute significantly to 2020 Jeep Gladiator reliability tips.
