Caterpillar Transmission/Drive Train Oil (TDTO)
Caterpillar Transmission/Drive Train Oil is balanced in order to give maximum frictional material life in power shift transmissions. Caterpillar Transmission/Drive Train Oil also eliminates brake chatter in wet brake applications in Caterpillar machines. This oil has passed the requirements for the TO-4 oil specification which includes the frictional requirements and gear wear requirements. This oil is offered in several lubricant viscosity grades. The SAE 60 viscosity grade is included for maximum component life at high ambient temperatures and for heavy-duty cycles.

This oil is formulated for transmissions and drive trains only, and should not be used in engines. Shortened engine life will result. |
Note: Do not use the Caterpillar Gear Oil or commercial gear oil in the final drives. The gear oil can cause seals to fail. The seals can also leak. The gear oil may not be compatible with friction materials. The oil can reduce the efficiency of the transmission and the brake performance.
Note: Multigrade oils must meet the requirements of the Caterpillar TO-4M specification in order to be used in transmissions. Multigrade oils which use high molecular weight polymers as viscosity index improvers may lose the viscosity effectiveness. This effectiveness may be lost by the temporary shear of the polymer viscosity index improver. Permanent shear of the polymer viscosity index improver may also occur. This type of multigrade oils are not recommended for Caterpillar drive train compartments. The Caterpillar TO-4M requirement includes a test for the shear stability of multigrade oil.
