Purpose and Specifications

Castrol Transmax Limited Slip LL 75W-140 1L is a full synthetic transmission oil designed for limited slip differentials and hypoid gears in high-performance vehicles. It meets API GL5, MB 235.61, ZFTE-ML 05C, 16G, and 18 specs, ensuring smooth operation from -40°C cold starts to over 200°C high-heat conditions.

This oil reduces axle noise and vibrations while providing exceptional protection under heavy loads like towing or racing. Its Smooth Drive Technology keeps it thick at extreme heat to prevent wear and thin enough at low temps for instant startup protection, extending axle life and allowing drain intervals up to 100,000 km or 5 years in severe duty.

• Key Benefits: Quieter smoother drive, maximum wear protection, high-temperature stability for longer component life
• Ideal For: BMW M-Series, Mercedes AMG, Ford Falcon, Holden Commodore, and competition vehicles
• Shelf Life: 5 years unopened when stored cool and dry

When to Use / Replace?

Use this oil in limited slip differentials during routine service, especially if you tow heavy loads, race, or drive in extreme climates. Replace every 50,000-100,000 km or 3-5 years for street use, or every 20,000 km for track/racing to maintain peak performance and prevent gear damage.

Check fluid level and condition every 10,000 km; dark color or metal particles signal immediate replacement.
