CMT™ is a blend of premium mineral and synthetic lubricants and meets the requirements for Caterpillar TO-4; Allison C-4*, CF-2 and CF; Eaton; and Dana manual transmissions.
CMT™ manual transmission fluid provides outstanding friction performance with both the metallic and nonmetallic friction materials found in today's hi-tech powershift transmissions. The frictional characteristics in Royal Purple's CMT™ eliminate excessive brake noise and prevent clutch slippage -- even under heavy loads on steep inclines.

CMT™ provides excellent low temperature fluidity for easier cold weather starting, superior corrosion and rust protection and maximum foam protection against entrapped air. This combined with Royal Purple's Synerlec® additive technology promotes greater oil life, smoother brake operation, reduced gear wear, controlled powershift transmission friction and more reliable equipment.

*CMT™ 30 meets or exceeds Allison C-4 requirements.
