Castrol Transmax ATF Dex/Merc LV Multi-Vehicle Automatic Transmission Fluid – 20L

Product Overview

Castrol Transmax ATF Dex/Merc LV Multi-Vehicle Automatic Transmission Fluid is a premium low-viscosity, high-performance transmission fluid designed to meet the requirements of modern automatic transmissions requiring DEXRON®-VI, MERCON® LV and similar low-viscosity ATF specifications. Formulated using advanced synthetic technology base oils and a carefully engineered additive system, this fluid delivers superior shift performance, enhanced fuel efficiency and long-term protection for critical transmission components.

Modern automatic transmissions operate with tighter tolerances, higher pressures and more sophisticated electronic controls than earlier designs. These systems require low-viscosity fluids that can flow quickly at start-up, maintain stable friction characteristics and provide consistent hydraulic response under all driving conditions. Castrol Transmax ATF Dex/Merc LV is engineered specifically for these requirements, offering rapid oil circulation, improved efficiency and excellent thermal stability.

The multi-vehicle formulation allows this fluid to be used across a wide range of passenger cars, SUVs, light commercial vehicles and fleet applications, making it an ideal solution for workshops and service centres seeking to reduce inventory complexity while maintaining high-quality servicing standards.

Supplied in a convenient 20-litre container, this product is well suited for professional automotive workshops, fleet maintenance operations and transmission specialists requiring reliable, bulk transmission fluid supply.
