Trans-C HT

Castrol Trans-C HT is a synthetic Hydraulic/Transmission fluid that balances high-temperature wear protection for gears and bearings with low-temperature flow properties. The result: positive shifting to protect against wear in low-temperature start-ups. It meets the requirements of Caterpillar TO-4 and is recommended for use where TO-4, TO-4M, C-4 and Vickers 35VQ25 is specified.

Extended Service Intervals

Castrol Trans-C HT successfully extends service intervals to more than 5000 hours in hydraulic systems and more than 2500 hours in power shift transmissions. It does so in various types of off road equipment without excessive wear or fluid degradation when supported by proper oil analysis.

Operational Efficiency

With its multipurpose formulation for both TO-4 10 weight and 30 weight applications, Castrol Trans-C HT simplifies maintenance practices and consolidates inventory.

Wear Protection

The excellent wear protection offered by Castrol Trans-C HT is further demonstrated during the ASTM D5182 FZG gear wear test. Castrol Trans-C HT achieved an 12 load stage pass delivering excellent wear protection at high loads giving increased component life. For you, that means reduced maintenance/repair costs with cleaner parts and operation.

Oxidation Stability

Castrol Trans-C HT formulation shows 25% better oxidation stability over typical anti-wear hydraulic oils. This means it can:

  • Withstand higher temperatures
  • Neutralize acidic decomposition
  • Provide greater assurance during  extended service intervals
