Castrol Transmax Manual Plus 80W-90 Manual Transmission Gear Oil High Load Protection Multigrade Durability Fluid 5L

• Viscosity Grade: 80W-90
• Fluid Type: Multigrade Gear Oil
• Industry Standard: API GL-4
• Container Volume: 5 Liters

Features

• Keeps manual transmission gear teeth protected under extreme high-load operating conditions
• Extends overall component service life by reducing internal mechanical wear and surface stress
• Delivers enhanced wear protection and fluid durability superior to standard monograde gear oils
• Maintains stable fluid operation and smooth shift characteristics across a broad temperature spectrum
• Prevents harmful deposit formation and thermal oil thickening during prolonged use

Applications

• Designed for manual gearboxes in passenger cars, commercial vehicles, and heavy-duty transport units requiring API GL-4 performance
• Lab-tested for synchronizer gear alignment and reduced gear-tooth pitting under high torsional torque loading
• Qualified for automotive drivetrain systems operating in fluctuating thermal environments

Usage

• Verify system fluid requirements and API GL-4 specification compatibility in your equipment manual prior to filling
• Drain old gear oil completely while warm to flush out wear contaminants before refilling
• Pour the recommended quantity directly into the transmission fill port until reaching the designated dipstick or plug line
• Check gear fluid levels regularly according to manufacturer service schedules to avoid oil starvation
• Inspect seals and transmission drain plugs periodically for signs of leakage or degradation
• Replace fluid at recommended service intervals to preserve optimal wear protection and shift smoothness
