It’s formulated to meet or exceed OEM requirements for manual gearboxes, synchromesh units, differentials, and certain transfer cases, while avoiding reactive sulfur chemistry that can harm brass synchros. The result is fast, precise shifting and comprehensive wear, corrosion, and seal protection under mixed driving conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this fluid improve shifting performance?\u003c\/h3\u003e\n\u003cp\u003eSynergy Gear MT combines friction modifiers with a stable viscosity profile to eliminate notchy shifts and reduce gear grinding. It maintains the correct frictional behavior for rapid synchronization without slipping, which helps achieve smooth, confident gear changes in both cold starts and warmed-up operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFriction modifiers tuned for synchromesh responsiveness\u003c\/li\u003e\n  \u003cli\u003eStable 204 viscosity index for consistent shift feel\u003c\/li\u003e\n  \u003cli\u003eArctic-grade pour point (-60°F) for immediate low-temp engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this protect yellow metals and internal components?\u003c\/h3\u003e\n\u003cp\u003eYes — the formula intentionally excludes reactive sulfurs and includes corrosion inhibitors that safeguard brass synchros, bronze bushings, and other yellow-metal components.
