Triax Manual Transmission Fluid 75W-80 GL-4 — Full Synthetic 1 Gallon, Synchromesh Protection

Designed from an ester and PAO base, this 75W-80 API GL-4 fluid delivers a stable friction profile, strong shear resistance and compatibility with brass and bronze synchronizers. It’s intended where manufacturers call for 75W-80 GL-4 or synchromesh oils — covering a broad list of OEM specifications from Ford, GM and Chrysler to VW/Audi, BMW/Mini, Mercedes-Benz, Honda/Acura, Nissan and others.

How does Synergy Gear MT improve shift feel during everyday driving?

The formulation is balanced for synchronizer dynamics so cone engagement is quick and consistent. That produces short, accurate shifts with minimal stick-slip even at cold start and under load. Over normal drain intervals the friction characteristics remain stable, reducing shift drift as the fluid ages.

• Tuned friction modifiers for crisp synchromesh engagement
• Fast shear recovery to prevent notchiness or hesitation
• Stable feel across temperature range and service life

Will this fluid protect synchronizers and soft metals?

Yes — Synergy Gear MT uses non-reactive sulfur carriers and magnesium-based modifiers that lubricate without attacking yellow metals. This helps guard brass and bronze synchronizers and related components from corrosive wear while maintaining the needed friction characteristics for synchronizing gears.

• Safe for brass and bronze synchronizers
• Corrosion-resistant additive set for soft metals
• Maintains protective film under sustained load

Is this oil suitable for high-heat, high-shear or performance use?

Because it’s built on full-synthetic PAO and ester base stocks, the fluid resists thermal breakdown and extreme shear better than conventional oils. It offers strong foam resistance and maintains a continuous lubricating film during extended or aggressive operation, making it suitable for both street and more demanding conditions.

• Full-synthetic PAO/ester base for thermal stability
• High shear resistance to protect gear oil film and viscosity
• Foam suppression for uninterrupted lubrication at high RPM
