CMT: Manual Transmission Fluid


  | Product Sheet

Royal Purple CMT commercial manual transmission fluid combines synthetic and high-grade mineral lubricants for the following manual transmissions:

  • Eaton
  • Caterpillar TO-4
  • Dana
  • Allison C-4, CF and CF-2

CMT TO-4 oil significantly reduces friction between the metallic and nonmetallic surfaces common in current sophisticated powershift transmissions. The synthetic commercial transmission fluid works to inhibit clutch slippage, especially under increased load pressure or on inclines. The friction-reducing formula curbs brake noise in industrial applications.

Royal Purple TO-4 oil allows for easier starts in cold weather due to its superior low temperature fluidity—another advantage is its ability to shift gears smoothly in cold climates.  It is available in SAE 10, 30 and 50 viscosities.

To purchase Royal Purple manual transmission fluid, locate a distributor near you.
