Eiffel Trans HD series is a range of extra high performance transmission and drive train oils, formulated with high quality base stocks and advanced additive system to meet or exceed the requirements of Caterpillar TO-4 specification. Suitable to provide heavy duty performance benefits in powershift transmissions, gearboxes, final drives and high pressure hydraulic applications. It helps in maximizing the productivity in construction, quarrying and mining equipment operating under severe conditions.
  • Balanced static and dynamic friction coefficients, help in optimizing clutch friction retention and control of slippage. Thus, ensuring increased load-carrying capacity & improvement in clutch life.
  • Good compatibility with various clutch materials and elastomers.
  • Excellent foam control property enhances the performance of wet brakes by controlling brake chattering.
  • Outstanding oxidation & thermal stability reduce high-pressure hydraulic pump wear and minimize sludge build keeping the application clean.
  • Outstanding anti-wear protection & load-carrying capabilities help reduce wear and extend the life of gearboxes, final drives, and transmissions.
  • Suitable for use in heavy-duty transmissions, gearboxes, final drives, and hydraulic systems used in off-highway applications including: mining, agriculture, construction, and quarrying.
  • Suitable for certain manual, powershift and automatic transmissions where Allison C-4 fluids (SAE 10W & 30 grades) are recommended.
  • Hydraulic applications in most mobile equipment


Eiffel Trans HD series meets or exceeds following International and Builder specifications:

  • Caterpillar TO-4
  • Allison C-4
  • Vickers M-2950-S
