The Red Line MT-90 75W90 GL-4 Manual Transmission Gear Oil is designed for manual transmissions, particularly those with synchromesh gearboxes. It offers superior protection for gears and synchro rings, leading to smoother, faster gear changes, even in cold conditions. A potential consideration is its specialized nature; always confirm it's the correct API GL-4 specification for your vehicle.

The primary benefit is significantly improved and smoother gear shifting, especially in cold conditions, along with enhanced protection for your transmission's gears and synchro rings.
No, Red Line MT-90 is specifically designed for manual transmissions and synchromesh gearboxes. It is not suitable for automatic transmissions.
GL-4 is an API (American Petroleum Institute) service classification for gear lubricants. It indicates the type and level of performance characteristics, specifically suited for manual transmissions with mild extreme pressure (EP) requirements and yellow metal (like brass) components.
Consult your vehicle's owner's manual for the manufacturer's recommended service interval. This can vary widely depending on the vehicle and driving conditions, but is typically between 30,000 to 60,000 miles for manual transmissions.
While technically possible, it is not recommended. Mixing different types and brands of gear oils can alter their performance characteristics and potentially lead to reduced protection or shifting issues. It's best to use only Red Line MT-90 once the transmission has been flushed.
Yes, Red Line is known for its performance lubricants. This MT-90 offers excellent protection and shift quality, making it suitable for spirited driving and many performance-oriented manual transmissions.
The amount of transmission fluid needed varies by vehicle. Refer to your owner's manual for the exact capacity. This product is sold in a 1 US Quart bottle.
Ensure the correct grade (75W90 GL-4) and quantity of oil has been used. Check for any physical obstructions or wear within the gearbox. Some very worn transmissions may not see a significant improvement.
Verify that the oil level is correct. Check for any damage to the gears or bearings. In some cases, this oil may help reduce noise, but it cannot repair mechanical damage.
Ensure drain and fill plugs are tightened to the manufacturer's specifications. Check the condition of the plug washers/seals and replace if necessary.
Compatibility: This oil meets the API GL-4 specification. It is recommended for use in transmissions requiring API GL-4, GL-3, GL-1, or where SAE 80W90, SAE 90, SAE 40W, SAE 10W40, or SAE 15W40 gear oils are specified. It is also listed as a direct replacement or equivalent for numerous manufacturer part numbers, including those from Audi, BMW, Ford, GM, Hyundai/Kia, Jeep, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Opel, Skoda, Toyota, Vauxhall, and Volkswagen. Always consult your vehicle's owner's manual to confirm the correct fluid specification before use.
Setup: Replacing transmission fluid typically involves draining the old fluid and refilling with the new. Ensure your vehicle is on a level surface and at operating temperature for optimal draining. Use appropriate tools to remove the drain plug and fill plug. Once drained, reinstall the drain plug and fill the transmission with the specified amount of Red Line MT-90 through the fill plug opening until it reaches the bottom of the fill hole.
Care: Transmission fluid does not have a defined shelf life if stored in a sealed container away from extreme temperatures and contaminants. However, the fluid inside your transmission requires periodic replacement. Refer to your vehicle's maintenance schedule for recommended fluid change intervals. Inspect for any leaks during regular maintenance.
