Triax DTF-1 Full Synthetic Transfer Case Fluid (1 Quart) — OEM DTF-1 Compatible, Shear-Stable All-Season Protection

Triax DTF-1 Professional is a full-synthetic transfer case fluid formulated to meet or exceed OEM specifications for modern on-demand and full-time AWD/4x4 systems.

Engineered for vehicles with electronically controlled wet clutch transfer cases and torque-vectoring AWD systems, this quart-size fluid replaces OEM DTF-1 and several factory part numbers while offering wide-temperature protection and shear-stable performance. It’s designed to ensure consistent clutch engagement, prevent shuddering, and protect internal components from wear across European, Asian, and American makes including Porsche, BMW, Audi, Mercedes-Benz, Land Rover, Nissan, and Genesis/Kia models.

How does Triax DTF-1 maintain smooth torque transfer in clutch-type transfer cases?

This fluid preserves friction characteristics over a broad temperature range so the transfer case control unit can meter torque predictably. Stable friction prevents clutch hunting and reduces the chance of shudder or chatter during tight turns or when engaging 4WD under load.

• Formulated for wet multi-plate clutches to retain consistent coefficient of friction.
• Shear-stable synthetic base minimizes viscosity breakdown during repeated slip events.
• Designed for ECU-controlled torque algorithms to keep engagement repeatable.

Will it work as a direct replacement for my vehicle’s specified fluid?

Yes — Triax DTF-1 is compatible with many factory specifications and direct-replacement part numbers. It’s intended for sealed 'lifetime-fill' systems and meets or surpasses the performance of several OEM fluids listed by manufacturers.

• Direct replacement for BMW DTF-1 and many Mopar/ACDelco part numbers.
• Meets requirements for MB 239.41 Torque-on-Demand and similar specs.
• Suitable for sealed transfer cases where lifetime fill is recommended.

How does this fluid perform in extreme temperatures and towing conditions?

Triax DTF-1 offers a true all-season formula that flows quickly in extreme cold yet resists oxidation and breakdown at high temperatures. That combination gives immediate clutch lubrication on cold starts and durable protection under towing, hard launches, and sustained high-speed driving.

• Rapid cold flow down to -60°F for reliable cold-start engagement.
• High-temperature oxidation stability for extended drain intervals under heavy duty.
• Protects chains, sprockets, and low-range gears during sustained loads.

Is Triax DTF-1 compatible with sensors, seals, and electronic components?

Yes — the formula is engineered to be compatible with modern elastomers, solenoids, sensors, and soft-metal components found in advanced AWD systems. Using the correct fluid helps avoid corrosion, seal swelling, or component sticking that can arise from incompatible lubricants.

• Safe for electronic sensors and solenoids used in active transfer cases.
• Formulated to be seal- and elastomer-friendly to prevent leaks or hardening.
• No adverse interactions with soft metals commonly used in transfer case internals.

Who is this product for: Triax DTF-1 Professional is suited for technicians, performance-minded owners, and fleet managers who service or operate vehicles with electronically controlled AWD/4x4 transfer cases that specify DTF-1 or compatible fluids. If you need a OEM-level, full-synthetic quart for precision torque control, temperature resilience, and long-term component protection across Porsche, BMW, Audi, Mercedes-Benz, Land Rover, Nissan, Genesis/Kia and similar platforms, this fluid is engineered for your application.
