This premium-grade ATF meets multiple international manufacturer standards including Ford MERCON LV, GM DEXRON-VI, and Aisin Warner specifications, making it a versatile choice for European, Japanese, and American vehicles.

The fluid is formulated to deliver smooth gear shifts, reduce friction, and maintain consistent performance across varying driving conditions.

The 5-liter canister format offers excellent value for transmission servicing or top-ups.

When to Use / Replace?

Transmission fluid replacement intervals typically range from 40,000 to 100,000 kilometers, depending on your vehicle manufacturer's recommendations and driving conditions. Most modern automatic transmissions benefit from fluid changes every 4 to 6 years, even if mileage is low. Check your vehicle's service manual for the exact interval.

Use this fluid when:

• Your transmission fluid appears dark or smells burnt (sign of degradation)
• You experience delayed gear engagement or rough shifting
• Your vehicle manufacturer specifies Ford MERCON LV, GM DEXRON-VI, or compatible ATF standards
• Performing routine transmission maintenance on compatible vehicles

This fluid operates effectively between -30°C and +100°C, ensuring reliable performance in cold winters and hot climates. Proper fluid levels and condition are essential for transmission longevity and fuel efficiency.

Frequently Asked Questions

Q: Can I mix this fluid with my current transmission oil?
A: Mixing different ATF brands is generally not recommended. Always drain the old fluid completely before adding CASTROL Transmax Multivehicle to avoid compatibility issues and reduced performance.

Q: How do I know if my vehicle is compatible?
A: Check your owner's manual for the required ATF specification (such as Ford MERCON LV or GM DEXRON-VI). This product covers a broad range of vehicles, but always verify compatibility with your specific make and model before purchase.

Q: What is the shelf life of unopened fluid?
A: Unopened CASTROL ATF typically maintains quality for 3 to 5 years when stored in a cool, dry place. Once opened, use the fluid within one season to prevent oxidation and contamination.
