Castrol Transmax Z


Automatic Transmission Fluid


Castrol Transmax Z is a high quality full synthetic transmission fluid. It is particularly recommended for use in automatic
and semi automatic transmissions used in buses and coaches. It may also be used in manual transmissions. As such
it is recommended for fleets employing a mixture of Voith, Renk, ZF, Allison and MB transmissions alongside the
Leyland Pneumocyclic and Hydracyclic units. Extended oil drain [120.000 km] in ZF Ecomat, MB AT and Voith AT

  • Excellent resistance to oxidation prolonging the life of the lubricant, offers extended drain potential and lowers
    operating costs.
  • Enhanced protection against deposits extends transmission life.
  • Temperature reduction in severe service improves transmission and oil service life and helps reduce fuel
    consumption and emissions
  • Optimised frictional characteristics providing smoother gear changes and protects against wear
  • Outstanding cold flow properties giving high protection to transmission especially at start-up
