Volvo Trucks is now offering an exclusive fully synthetic SAE 75W-80 transmission fluid for its I-Shift automated manual transmission that – depending on vehicle model and application – is approved for drain intervals up to 500,000 miles.

A similar fluid is also being rolled out for the mDrive automated manual produced by its brother company, Mack Trucks.

Chris Stadler, product manager at Volvo Trucks, said this new synthetic fluid is designed to help the I-Shift maintain its peak operating efficiency – delivering the correct frictional responses, material compatibility and unique viscosity grade needed for optimized fuel economy and fluid durability demanded by automated manual transmission models.

He added that the fluid’s 75W-80 viscosity grade helps it maintain its fuel efficiency benefits through reduced “viscous churn,” smoother gear meshing and easier pumping and filtering.

“The high viscosity index allows for outstanding low-temperature fluidity for quicker starts, easy shifts and reduced wear during cold start-ups while providing strong lubricating films at higher temperatures,” Stadler pointed out. “More stable and optimized friction properties ensure smooth and rapid gear shifting, reducing stress on the driveline and tires.”

The new SAE 75W-80 I-Shift transmission fluid is available in both five-gallon pails (VP0120548) and four one-gallon jugs (VPO120549), he added.
