Castrol TRANSMAX Universal Long Life 75W-90 is a full synthetic transmission fluid recommended for most commercial vehicle manual transmissions where API GL-4 / GL-5 lubricants are required. These transmissions are generally larger and subjected to higher loads and temperatures than those in passenger cars. TRANSMAX Universal Long Life 75W-90 was developed for these particular requirements and is approved by a number of manufacturers.

Features & Benefits:

• Excellent oxidation stability makes it suitable for high temperature and extended drain service.
• Proven synchroniser performance makes gear shifting easier and transmission operation quieter.
• Very fluid at low temperatures for easier cold start gear shifting in synchronised transmissions.
• Good wear and EP performance ensures component protection under high load conditions reducing downtime and service costs.
• Compatible with normal mineral oil, hence no special flushing procedure is needed when changing from mineral to synthetic oil.
• Long drain performance – potentially lower maintenance costs and greater vehicle availability.
• Specially selected synthetic base fluids and additive system - very stable viscosity in service.

Industry Specifications:

• API GL-4
• API GL-5
• MT-1
• SAE J2360
