In 2001, Volvo Corporation introduced the I-shift gearbox for the first time in the long-distance bus market. In 2005, Volvo redesigned the gearbox, including the new clutch system and the new second-generation I-shift gearbox. Compared to the first generation, the second-generation I-shift can adapt to larger loads and can be adapted to engineering vehicles and forest road transportation. In addition to the previously matched 9-liter and 12-liter engines, it can also match the 16-liter engine.
Europe is about to implement the Euro VI emission regulations. Not only the engine, but also the gearbox technology must be upgraded. The next generation of Volvo products will help vehicles to further reduce fuel consumption. 
Volvo I-shift AMT (electronically controlled automatic transmission) gearbox
The Volvo I-shift is a 12-speed AMT transmission that maximises driving comfort, payload and fuel economy, and is perfectly matched to all Volvo truck models. With the help of a computer program, the Volvo I-shift automatically adjusts gears based on factors such as grade, speed, accelerator pedal condition, required torque, total vehicle weight, and air resistance. As the engine and gearbox interact with each other, the gears The choice is accurate. Volvo I-shift automatically selects gears that are suitable for the operating conditions of the engine, eliminating the driver’s differences in driving experience, allowing everyone to obtain the best fuel economy, while also alleviating the work pressure of the transmission system, and providing a longer service life. Long, less maintenance required. 
Volvo I-Shift tiptronic gearbox
Volvo I-Shift manual transmission has E/P mode, E(Economy) economic model is suitable for long-distance high speed working conditions, P(Performance) power mode can provide more powerful power under heavy load and uphill conditions. . When the driver wants to walk from the seat to the middle of the cab, the vertical joystick of the gear box will block. Press the folding button to level the lever and the driver can walk freely.
There is also a L (Limp home) limp home mode behind the I-Shift manual transmission. Its role is that the gearbox can still keep the gearbox in a stall and slowly travel to the service area in the event of an electrical fault. Maintenance will not be trapped halfway
Extensive reading:
The electronically controlled mechanical automatic transmission (AMT) is an improvement over the conventional manual gear type transmission; it incorporates both electromechanical and hydraulic integrated automatic transmissions with both AT (automatic) and MT (manual) advantages; AMT With the advantages of automatic transmission of hydraulic automatic transmission, it retains the advantages of high efficiency, low cost, simple structure and easy manufacturing of the original manual transmission. It combines the advantages of both, it is very suitable for China's national conditions of electromechanical hydraulic integrated automatic transmission. It is rebuilt on the current production of mechanical transmission, retaining most of the original assembly components, only changing the manual shift lever of the operating system, the production of good inheritance, the transformation of the input costs less, very easy to be produced Accepted by the factory. Its disadvantage is non-power shifting, which can be compensated by electronic control software. In several automatic transmissions, AMT is the most cost-effective.
