How does this fluid support transmission performance?

The synthetic formulation is balanced for stable viscosity, controlled shear characteristics and consistent friction behavior to promote smooth gear shifts and reliable hydraulic operation. It helps maintain operating temperatures and resists breakdown under heavy use.

• Stable viscosity across a wide temperature range for dependable lubrication
• Designed friction properties for crisp, consistent shift feel
• Thermally resilient to reduce oxidation and deposit formation

What are the practical service benefits of buying a 7-liter container?

A 7 L container is sized for full fill or multiple partial services depending on the transmission’s sump capacity. It’s cost-effective for workshops and DIYers who service multiple vehicles or require extra fluid for flushes and top-ups.

• Large volume suited for single full-fill applications on many transmissions
• Useful for frequent maintenance or multi-vehicle shops to reduce reordering
• Sealed packaging simplifies storage and spill-free pouring during service

Are there any safety or regulatory notes I should know?

Use normal workshop precautions: avoid prolonged skin contact and inhalation of mists, and follow local disposal rules for used transmission fluid. This product carries regulatory notices in certain jurisdictions; consult safety data sheets for full handling and environmental information.

• Follow vehicle manufacturer service intervals and disposal guidance
• Review the SDS for handling, first-aid, and environmental precautions
• Store sealed, upright, and away from direct heat or open flame
