Red Line Synthetic MTL 70W80 GL-4 Gear Oil: Manual Transmission Fluid | 50204

Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection. Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
Red Line offers lubricants to pinpoint nearly every transmission application
Details:

• Sold as 1 Quart
• MTL, MT-85 and MT-90 are not for use in differentials with hypoid gears
• Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
• Excellent for high- and low-mile transmissions
• Compatible with petroleums and other synthetics
• Popular for BMW, Honda/Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge and Jeep NV1500, NV3500 , NV3550 and NV5600 truck transmissions
• Popular replacement for and improvement over GM Synchromesh (12345349), Auto-Trak II (12378508) and Chrysler spec MS-9224
• Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
• Offers quicker shifts, A perfect synchronizer coefficient of friction
• Eliminates notchy shifting, even when cold
• High performance gear protection and longer synchro life
