Premium Synthetic Lubricant Improves Performance of Eaton Roadranger & Other Manual Transmissions

Synolec® Transmission Fluid (640) is a premium full synthetic lubricant designed for fuel efficiency and extended drain intervals while meeting OEM warranty requirements. It is intended for use in manual transmissions that require a non-EP transmission fluid for light- to severe-duty, on- and off-highway equipment operating in a diverse range of environments. Formulated to protect higher torque transmissions coupled with increased horsepower engines, it will prolong transmission life by reducing gear wear and copper corrosion.

Synolec Transmission Fluid meets or exceeds the specifications of several manual transmission OEMs, including Eaton transmissions such as Roadranger, Ultrashift Plus, Fuller Advantage, FR and RT Series.
