TRIAX Synergy Gear MT 75W-90 is a full-synthetic manual transmission fluid built for gearboxes and transaxles calling for API GL-4 — and built to be safe for the brass and bronze synchronizers that GL-5 hypoid oils attack. Non-reactive sulfur carriers and magnesium-based friction modifiers protect gear teeth without corroding soft metals, while the friction profile is tuned to synchronizer dynamics: the fluid shears away fast enough to let the cone engage, then carries load the instant it does. The result is short, precise, repeatable shifts — no notchiness on a cold morning, no baulking under torque, no drift in feel as the fluid ages. With specification coverage spanning fifteen North American, European, and Asian OEMs, one fluid consolidates the majority of 75W-80 GL-4 manual transmission and transaxle applications.

• WIDE RANGE OF NORTH AMERICAN, EUROPEAN, AND ASIAN OEMs — Suitable for use where the following are required: VW/Audi G 052 911, G 005 000, 501.5 · BMW MTF-LT-4 · Mercedes-Benz 235.11 · Ford M2C175-A, XT-4-QGL · GM/GM-Daewoo 12345871, 89021806 · Toyota 08885-80917 · Mazda (MES) 115A · Hyundai/Kia 08950-00010-A · Nissan Mission Oil MP-G HQ · Jeep 0489722AA · New Venture Gear NV 4500 - and many other applications.
• API GL-4 75W-90 - For street, track, and heavy-duty applications.
• SUPERIOR SHIFT QUALITY - NO STICK / SLIP - SMOOTH SYNCHRO ENGAGEMENT — The friction profile is tuned to synchronizer dynamics: the fluid shears away fast enough to let the cone engage, then carries load the instant it does. Short, precise, repeatable shifts — no notchiness on a cold morning, no baulking under torque, and no drift in feel as the fluid ages.
• SAFE FOR BRASS AND BRONZE SYNCHRONIZERS — Non-reactive sulfur carriers and magnesium-based friction modifiers protect gear teeth without attacking yellow metals, helping guard synchronizers and other soft-metal components against corrosive sulfur damage through the full drain interval.
• HOLDS UP UNDER HEAT, SHEAR, AND CHURNING — Full-synthetic construction delivers extreme shear stability under sustained gear mesh, superb foam resistance for a continuous lubricating film at high speed, and a wide operating temperature range. Broad compatibility with natural and synthetic elastomers, plus excellent lubricity for quieter, smoother gear operation.

Available Viscosity Grades: 75W-80, 75W-90
