Trans Oils are specialised Transmission and Drive Train Oils (TDTO) which have been formulated to meet the special requirements of the Caterpillar TO-4™ (2005 revision) specification. They greatly reduce gear wear, improve friction control, promote long life in transmissions and brakes, and ensure less brake noise and increased rimpull. Trans Oils are not compromise fluids as are conventional powershift fluids, which are fundamentally engine oils meeting the former less restrictive CAT TO-2™ and Allison C-2 specifications.
The individual additive components of Trans Oils were specially selected to balance and control the friction performance of the materials comprising the metallic and the newer non-metallic clutch surface materials.
The frictional properties uniquely provided by Trans Oils overcome problems of excessive brake noise, weakening of the binders in paper surface materials and embrittlement of elastomeric materials. Trans Oils stable friction properties eliminate clutch slippage even under heavy loads on steep inclines. There is no need to constantly adjust equipment to maintain clutch settings. The excellent anti-oxidation properties of Trans Oils together with the resistance to sludge formation provide longer oil drain intervals and far more reliable equipment operation.
The low temperature fluidity of Trans Oils ensures easier cold weather starting and improved wear protection with low temperature start-ups. Long term anti-wear protection to gears and bearings is assured by the inclusion of special anti-wear additives. The foam inhibitors in Trans Oils provide effective protection against foam development thus avoiding metal-to-metal contact and further minimising wear. Long term rust and corrosion protection to steel and copper-based metal is assured by the inhibitors in Trans Oils.
