Royal Purple Synchromax Transfluid 1 Quart (32 oz) Synthetic Low-Viscosity Gear & Transmission Fluid for Smooth Shifts

Engineered with Royal Purple’s proprietary Synerlec additive technology, Synchromax blends synthetic base oils and friction-stable chemistry to improve shift feel, reduce gear noise and protect components across a wide temperature range. It is formulated to be compatible with a variety of friction materials and soft metals commonly found in synchronizers while resisting oxidation and corrosion for long service life.

How does Synchromax improve shift quality?

Synchromax uses a friction-modified synthetic formula that helps synchronizers engage more smoothly, reducing grinding and harsh shifts. The Synerlec additive package stabilizes friction characteristics as temperatures change, so shifts remain consistent in cold starts and high-heat operation.

• Synerlec technology for stable friction behavior
• Light-viscosity synthetic base oils for faster response
• Designed to minimize shift shock and gear clash

Will this fluid protect gears and synchronizers?

Yes — Synchromax provides enhanced wear protection and resists oxidation and corrosion to help extend component life. It is formulated to protect both hardened gear surfaces and the softer metals found in many synchronizer assemblies without compromising friction performance.

• Greater wear protection than conventional ATFs
• Oxidation resistance to reduce varnish and deposits
• Compatible with soft synchronizer metals and friction materials

Which applications is Synchromax suitable for?

Synchromax is recommended for manual transmissions that specify automatic transmission fluid or other light-viscosity oils, and it also works well in transfer cases and 2-cycle motorcycle gearboxes calling for light lubricants. It’s a versatile choice when equipment requires a friction-stable, low-viscosity synthetic fluid.

• Manual transmissions specifying ATF or low-viscosity oils
• Transfer cases requiring light-viscosity lubricants
• 2-cycle motorcycle gearboxes that call for ATF-style fluids

How do I use this quart bottle and what are its specs?

The product ships in a 1-quart (32-ounce) bottle for easy pouring during service or top-up. The package is compact and lightweight, making it convenient for storage or keeping a spare bottle in the garage for maintenance.

• Volume: 1 quart / 32 ounces
• Package dimensions: 28.575 H x 8.636 L x 8.89 W (centimetres)
• Package weight: 0.839 kilograms; made in the United States

Who is this for? Synchromax is aimed at vehicle owners, mechanics and riders who need a reliable, synthetic light-viscosity fluid for manual gearboxes, transfer cases or 2-cycle motorcycle gearboxes that specify ATF-type or low-viscosity oils. If you want improved shift feel, reduced gear noise and robust wear protection without risking compatibility with synchronizers or soft metals, this product provides a targeted, workshop-ready solution.
