Transmission
Transmission and drivetrain oils cover a wide range of applications including powershift transmissions, automatic transmissions, final drives, and universal tractor transmission oils (UTTO). Key specifications include Caterpillar TO-4 for heavy equipment, Allison TES 295/668 for automatic transmissions, and John Deere J20C for agricultural machinery. These specialised fluids must meet precise friction requirements to ensure proper clutch engagement, smooth shifting, and component longevity.

Frequently Asked Questions
What is TO-4 transmission oil used for?
Caterpillar TO-4 (Transmission/Drive Train Oil, 4th generation) is a specification for oils used in powershift transmissions, final drives, and hydraulic systems of heavy equipment. TO-4 oils provide specific friction characteristics required for proper clutch engagement in Caterpillar and other off-highway equipment.
Can I use UTTO (Universal Tractor Transmission Oil) in all tractor systems?
UTTO oils are designed to serve multiple functions in agricultural tractors — transmission, hydraulics, wet brakes, and power take-off. However, not all tractors accept UTTO. Always check the tractor manufacturer’s specifications. Some newer tractors require separate fluids for each system, and using UTTO where not specified can cause operational problems.
What is the difference between Allison TES 295 and TES 668?
Allison TES 295 is a specification for synthetic automatic transmission fluids designed for Allison on-highway transmissions, offering extended drain intervals. TES 668 covers a broader range of fluids including some conventional formulations. TES 295 fluids typically provide better oxidation resistance and longer service life than TES 668 approved fluids.
What does JDM J20C mean on a transmission oil label?
JDM J20C is a John Deere specification for transmission and hydraulic oils used in John Deere agricultural and construction equipment. It defines the friction, wear, and compatibility requirements for the oil to function properly in John Deere powershift transmissions, wet brakes, and hydraulic systems.
