MTL 75W80 GL-4 Gear Oil

Red Line MTL 75W80 GL-4 Gear Oil is engineered for superior performance in manual transmissions, delivering optimal synchronizer friction for smooth, quick shifts and long-lasting gear protection. This fluid is a direct OEM replacement for Mini Cooper S LSD gearboxes and is widely used in BMW, Honda/Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Mitsubishi, Dodge, and Jeep NV1500, NV3500, NV3550, and NV5600 truck transmissions.

• Excellent replacement and upgrade for GM Synchromesh (#12345349), Auto-Trak II (#12378508), and Chrysler MS-9224 specifications.
• Safe for brass synchronizers—formulated without reactive sulfurs found in most GL-5 oils, preventing damage to soft metals.
• Reduces notchy shifting, even in cold conditions, and provides consistent synchronizer performance.
• Delivers high-performance gear protection and extends synchronizer life.
• Meets gear oil viscosity requirements of 75W, 80W, and engine oil viscosities of SAE 30, 10W30, and 5W30.
• Recommended for GL-1, GL-3, and GL-4 applications, as well as most special synchromesh fluid requirements.

Features

• Precisely balanced coefficient of friction for proper synchronizer engagement—many synthetic gear oils are too slippery for optimal performance.
• Not for use in differentials with hypoid gears (MT-LV, MTL, MT-85 & MT-90).
• Performs reliably in both high-mileage and low-mileage transmissions.
• Compatible with petroleum and other synthetic lubricants.
