This racing-grade fluid is formulated specifically for high-load mechanical transmissions, including synchronized or non-synchronized manual gearboxes, transaxles, transfer cases, and heavy-duty hypoid differentials equipped with integrated limited-slip (LS) systems.\u003c\/p\u003e\n\u003cp\u003eFeaturing absolute shear stability, Motul Gear Competition guarantees 0% shear loss, maintaining an unbreakable protective oil film even under aggressive shock loads, high torque at low speeds, or prolonged high-RPM track conditions. The high SAE 140 hot viscosity rating delivers outstanding thermal film resistance to substantially reduce mechanical friction, drivetrain wear, and gear whine under extreme heat. Meanwhile, its optimized low-temperature fluidity ensures smooth, effortless gear shifting on cold starts and tight out-lap warmups.\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003eWhat's In The Box?\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Motul Gear Competition 75W140 Transmission Oil – 1L Bottle\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cb\u003eFrequently Asked Questions (FAQ)\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cb\u003eQ: When should I choose 75W140 over 75W90 for my gearbox or differential?\u003c\/b\u003e A: A 75W140 fluid is preferred for drivetrains subjected to extreme heat, heavy endurance environments, or high shock loads (such as drift, rally, or heavy track cars). The heavier hot weight provides an extra layer of film protection and reduces transmission chatter or noise under extreme stress compared to a 75W90.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Is this product compatible with plate-type limited-slip differentials?\u003c\/b\u003e A: Yes, Motul Gear Competition features integrated friction modifiers designed specifically for limited-slip systems. It allows smooth locking operation without stick-slip or clutch plate shudder in performance differentials.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eQ: Does this fluid meet API safety ratings?\u003c\/b\u003e A: Yes, it is fully rated for API GL-5 specifications, making it perfect for high-load hypoid final drives, performance gearboxes, and transaxles requiring extreme-pressure lubrication.\u003c\/p\u003e","brand":"Motul","offers":[{"title":"Default Title","offer_id":54702825341257,"sku":"450086","price":30.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/9463\/0729\/files\/450086_1_59137676-cb39-46ce-b929-c1377f2e90c4.png?v=1782116937","url":"https:\/\/rrs-store.co.uk\/products\/motul-gear-300-ls-75w90-synthetic-racing-transmission-oil-1-litre","provider":"Race Rally Supplies","version":"1.0","type":"link"}
