Product Data Sheet


NOCO Nortrans HD Series are specialized transmission fluids formulated to meet Caterpillar TO-4 specification. The Nortrans HD 10W and 30 also meet the Allison C-4 specification. These fluids are designed to give smooth transmission power transfer under high horsepower conditions.

NOCO Nortrans HD oils are suitable for the old Caterpillar TO-2 specification, but provide substantially improved friction and anti-wear performances, resulting in longer equipment life. They also provide excellent low temperature properties and oxidation stability, meaning easier cold weather startups, oxidation protection, and wear and sludge control. NOCO Nortrans HD is also suitable for engines requiring API CF and CF-2.
