Trans-C

Castrol Trans-C combines a high viscosity index base oil with select additives to maximize transmission life under severe, high-load conditions.

In Caterpillar transmission, where paper and elastomer disc materials are used, Castrol Trans-C provides the right balance of frictional performance with its proprietary friction modifiers. It excels in many on- and off-highway transmission and hydraulic applications and is approved for use under Caterpillar TO-4, Allison C-4 and Vickers 35VQ25 specifications.

Wear protection is critical in driveline fluids. In the ASTM D4998 FZG test where gear teeth wear is measured, Castrol Trans-C 50 and Castrol Trans-C 60 improved wear protection versus other competitive mineral grade TO-4 fluids providing enhanced protection to final drives and increased component life.

Castrol Trans-C helps you to:

  • Prolong equipment life with improved friction  and anti-wear performance
  • Reduce downtime by eliminating friction degradation  and clutch slippage
  • Reduce component failure by preventing sludge  and deposit formation
  • Resist wear on final drives to provide a margin of safety during sever operations
  • Extend drains with regular oil analysis
  • Decrease fluid overflows and provide safe work environment
  • Increase worker and equipment productivity with fast start-up during cold temperatures
