"The first Volvo FM480 with Allison was a 'sensational' effect with extraordinary performance," said the Swedish company Hall. Due to the high efficiency in operation and the outstanding performance of ramping at full load, the Volvo gravel truck with Allison transmission was highly praised in Sweden. Halls Brothers of Hassleholm was the first company to specify the Allison transmission as part of the Volvo FM480 truck that it purchased. After using it for a year, this sandstone company has already reported high efficiency and low cost. The former company of Hall Brothers was an agricultural harvester company established in the 1920s. This family has been passed on to the fourth generation. Currently they are operating the first stone crushing plant in Europe and employ 38 employees to run the company. The gravel material was mined from three company-owned quarries, while sand and gravel materials were mined from their other four gravel yards. Currently, the Hall Brothers produces 500,000 tons of ballast each year, of which approximately 400,000 tons are directly transported to customers by themselves. “When we purchased Volvo, we initially chose the Allison automatic gearbox with retarder and the FM480 with VEB Volvo's intelligent engine brake,†said Kent Hall, finance manager of Hall Brothers. Says, "This is the first Volvo FM480 gravel truck equipped with Allison transmission. Its performance can be described as 'sensation'." Hall also summarized Allison's other advantages. With the Allison fully automatic transmission, driving is smoother, which protects the entire driveline. Hall said, "We definitely saved a lot of money while reducing vehicle maintenance time." The 13-litre FM480 recently acquired by Hall Brothers has demonstrated excellent traction thanks to the assembly of the Allison 7-speed 4700R automatic gearbox. "The uninterrupted shifting of power to the torque converter and the power make the engine power transmission smooth, There was no vibration at all," Hall said. “This would make it a breeze to start a full-loaded gravel truck on a steep slope of 14%. The extra planetary gearset and 4.5 rear axle ratio of the rear axle ensure that we can perform best in difficult tasks. The truck is also It exhibits good road and off-highway performance. It achieves maximum production efficiency at low speed and high torque during gravel pit operations and achieves the best fuel economy on the highway,†said Hall. The Volvo driver Lars Anderson was equally impressed with this: "It's very comfortable to drive a fully automatic gearbox. It starts gently and the tires don't slip in the gravel pit. I almost don't feel the shift. Even if the car is full of cargo, it can start smoothly on steep slopes, which guarantees the safety of driving. Allison Transmission has completed all the things for you so that you don’t have to shift gears to concentrate on driving vehicle." Anderson also noticed the advantages of Allison compared to AMT. "The engine of the AMT vehicle loses power every time it is shifted, but the Allison automatic gearbox never has a moment of power interruption," he concluded.

“The Scania vehicle with Allison products is a very positive case that caused the automatic gearbox to draw the company’s attention,†explains Peter Hansen, who drove the car. “We always use Volvo trucks. The Scania G480 we bought was just trying to test the Allison automatic gearbox. However, after we used this car for a year, the performance of the Allison transmission made us all excited."
