Penske Truck Rental is adding 500 new Freightliner semi-tractors to its commercial truck rental fleet featuring Eaton’s UltraShift Plus Multipurpose High Performance (MHP) Automated Transmissions.
Built upon Eaton’s Fuller 13- and 18-speed manual transmissions, the UltraShift Plus Performance Series uses an electronic clutch actuator to provide faster shifting and smoother engagement. Intelligent shift selection software uses changes in grade, weight and throttle to calculate the most efficient and effective shift points. The UltraShift Plus fully engages the clutch at idle, giving the driver control in challenging situations.
“We’re pleased to introduce this new automated transmission as a value-added feature for our commercial rental customers and their truck drivers,” said Penske’s Don Mikes, Senior Vice President of Rental. “Smooth shifting automated transmissions offer fleet operators improved fuel economy and an added dimension of safety as the truck driver’s hands stay on the wheel versus shifting manually."
