Volvo Truck’s I-Shift Transmission

Wednesday, December 2nd, 2009

Never before has a transmission received such a positive response from drivers and transport companies all over the world. Today 60 per cent of all Volvo FH trucks are sold with I-Shift and it is standard in the world’s most powerful series production truck, the Volvo FH16 700 hp.Volvo I-Shift TransmissionThe I-Shift’s predecessor, Geartronic, was not an optimised solution and an automatic transmission was needed to enhance driver comfort and driving ease. At the same time, the development of electronic systems really took off at the end of the 1990s. More and more of these improved systems were used to control both the engine and the rest of the truck and this created new opportunities to develop an electronically controlled transmission.

Gearchanging can be done manually or automatically. “Performance” mode gives maximum power and best drivability in automatic, while “Economy” mode gives priority to low fuel consumption. In manual operation, gearchanging is done with a button on the gear lever.

The updated I-Shift transmission gives improved functionality on soft grounds, found in construction and timber segments, via the P+ performance mood that optimize gear shifting for these applications.

Faster declutching. Makes it easier for the driver to rock the truck out of difficulty if it gets bogged down.
