The reinforced I-Shift automated manual transmission for severe-duty (SD) applications will be available for order in May in Volvo VHD vocational models. The I-Shift for severe duty is designed for on- and off-road work in construction and other applications requiring frequent shifting. It is available on VHD models powered by the Volvo D11 and D13 engines and is standard on VHD models with heavier weight ratings – straight trucks rated at 66,000 lbs. GVWR or higher and tractors rated at 125,000 lbs. GCWR or higher. For lighter weight applications, VHD customers can select this version of the I-Shift SD as an option.

“With this new rugged Volvo I-Shift, we now offer the efficiency and productivity benefits of our automated manual transmission and integrated powertrain to customers operating in tough vocational applications while providing improved uptime and longer component life,” said Gӧran Nyberg, president of Volvo Trucks North America. “Volvo Trucks is committed to delivering solutions tailored to our customers’ specific applications.”

Gears and other hardware in the severe-duty I-Shift have been hardened to withstand frequent shifting in a rugged operating environment. In addition to the hardened gears, this version features a high-range hardened cone, improved split synchronizer components and main box parts fashioned from reinforced material.

The I-Shift SD uses higher-viscosity oil that allows for operation at a higher ambient temperature, and it features a new transmission cooler mounted to the transmission. Reduced oil line length and quick-disconnect fittings improve serviceability since there is no need to drain oil in order to service or remove the transmission.

“The heavier loads, uneven terrain and frequent shifting typical of heavy-duty vocational duty cycles require a more rugged transmission,” said Chris Stadler, Volvo Trucks regional haul marketing manager. “The reinforced components and improved serviceability of the I-Shift for severe-duty applications translate to lower maintenance costs and more time on the work site producing revenue. The transmission also offers customers a broader payload range, which can help enhance the truck’s profitability and versatility."
