Volvo I-shift is an entirely new gearbox based on the manual gearbox’s dependable design. It features an integrated gearchanging system and all functions are electronically controlled. You can choose if the system should change gears entirely automatically or manually. The gear lever is attached to the driver’s seat, so it is always within convenient reach no matter how you adjust the seat. All the manual range-change and splitter gearboxes now feature Volvo’s patented servo synchro system (further refined in the new gearboxes) which reduces gearchanging forces by up to 50%. The new Volvo FH and FM also have an entirely new gearchanging system with cable-operated controls. It gives shorter and more distinct gear lever movements and low shift forces. In addition, noise and vibration via the gear lever have been eliminated.
SAFER THAN EVER BEFORE Volvo’s automatic transmissions – Powertronic, Geartronic and I-shift – have functions that integrate with the various auxiliary braking systems (VEB, hydraulic compact retarder and primary retarder for Powertronic) and with the truck’s wheel-brake system. With a stalk on the steering column, you can determine the auxiliary brake’s application power conveniently and simply. You can also decide if the auxiliary brake should be activated when you press the brake pedal, or whether the transmission should automatically change down to raise engine speed and thus provide the maximum effect.

EASIER TO POWER ANCILLARY EQUIPMENT THAN EVER BEFORE There are engine-driven power takeoffs with a direct-driven hydraulic pump for both the Volvo D12 and D9. The power take-off for the new Volvo D9 engine is powered directly from the rear of the engine and thus permits a high power output. Propshaft drive with an SAE flange is also available as an alternative. You can also obtain high power on the move with a flywheel-driven power take-off (FM12). The fully-automatic Powertronic transmission has an integrated PTO system that provides a high power output via a multi-plate clutch. The new Volvo FH and FM also feature a comprehensive range of gearbox-driven power take-offs for direct drive of a hydraulic pump or via a flange for propshaft drive. The power take-offs are tailored for Volvo’s gearboxes and can also be used in combination with Volvo’s hydraulic compact retarder. They are available in a low-speed and a high-speed configuration, allowing you to power up to three different applications.

I-SHIFT – INTELLIGENT GEARBOX The new Volvo FH and FM are available with an entirely new gearbox featuring a fully automatic gearchanging system and 12 forward gears. It is the perfect choice for distribution and long-haul operations on good roads with gross combination weights up to 44 tonnes. Full electronic control gives you considerable flexibility in switching between automatic and manual gearchanging if required. I-shift also improves safety levels and contributes to lower fuel consumption. In addition, it is about 70 kg lighter than the corresponding manual gearbox.
AUTOMATIC TRANSMISSION BASED ON MANUAL GEARBOX
TOTAL CONTROL
I-shift is tomorrow’s automatic transmission, designed around the manual splitter gearbox’s simple and dependable mainshaft, lay shaft and reverse shaft construction. The aluminium base unit has three nonsynchromesh gears and a synchromesh splitter gear which together with the range-change offers a similar system to the manual gearbox. Like our manual boxes I-shift features an oil filter, gear-driven oil pump, oil cooler (option) and auxillary steering pump for twin front axles I-shift can accomodate a PTO and hydraulic retarder. The electronic system that governs gearchanging is well protected in a control housing that also contains the system’s solenoid valves, operating cylinders, shift forks, sensors and other functions, where gearchanging is carried out with the help of compressed air. I-shift is 70 kg lighter than a corresponding manual gearbox. Aluminium is used for the various housings: the bell housing, base and range unit casing and control unit housing. The synchromesh system for the base gears has been replaced with electronic control and there is no crawler gear in I-shift. The net effect is reduced weight.
The gearchanging function is electronically integrated with the truck’s other system functions, and interacts for instance with the engine and braking systems. You can choose between various control programs for I-shift depending on your current needs. In addition to the standard program, there is a “Fuel Economy” program which is mainly intended to improve fuel consumption, as well as a “Comprehensive” program with additional functions. “Fuel Economy” gives you access to the following functions: ■ Automatic choice of starting ratio based on gross vehicle/combination weight and gradient. ■ Intelligent control of power when you select the P program. ■ Maximum engine braking effect through automatic down-changes (when you move the control lever beside the steering wheel to its rearmost setting). ■ Automatic control of engine braking at low speeds.
“Comprehensive” program means that the “Fuel Economy” program is extended to you another three practical features: ■ Maximum power and engine speed via a “kickdown” function on the accelorator pedal. ■ Oil temperature gauge and warning system. ■ Electronic system that indicates in the driver’s information display when it is time to replace the clutch plate.

QUICK, PRECISE GEARCHANGING I-shift changes gear smoothly and quickly, and with considerable precision. Since the base gears do not feature synchromesh, gearchanges are quicker. The engine’s compression brake is used automatically at each gearchange to retard the engine. If you want to maintain high speed, engage the cruise control and let it take care of all the gearchanges.

THE GEAR LEVER ACCOMPANIES THE SEAT AS IT IS ADJUSTED
INTEGRATED BRAKING FUNCTION
The gear lever is attached directly to the driver’s seat. It is compact and neat, and is always in the right place, even if you move the seat. You can choose between fully automatic shifts and “manual” gearchanges by activating a rocker switch on the gear lever. If you are driving in the automatic (A) mode, you can at any time move the lever backwards to the Manual (M) mode and temporarily block further changes, or you can switch to manual gearchanges – a feature you will appreciate in certain operating conditions. The gear lever can also be conveniently tucked down out of the way to permit unobstructed movement inside the cab. At the press of a button, you can choose between two modes – E (Economy) and P (Performance). E allows you to drive with maximum fuel economy. With P, you exploit the engine’s higher revs before changing gear, allowing you to accelerate faster when conditions require. You can monitor the gearchanging function on the driver’s display, which shows which gear is currently engaged, the current driving program and which gears are available to select.
I-shift functions like an automatic transmission and permits more relaxed driving in hectic operating conditions. The gearchanging system interacts with the truck’s other braking systems. If you have specified the optional VEB (Volvo Engine Brake) you always have access to high braking power, and with Volvo’s hydraulic compact retarder, braking power is even greater. The auxiliary brake (VEB, retarder) is operated via a control stalk beside the steering wheel. You can choose between various output levels, or you can select automatic activation together with the truck’s wheel braking system when you press the brake pedal. The automatic setting also offers an additional feature when driving downhill the electronic system takes over, regulating the auxiliary brake’s effect to suit gradient and your selected speed. The gear lever also has a position which gives you swift access to maximum braking effect since the I-shift system automatically changes down to raise engine speed (option).
MATCHED TO EACH INDIVIDUAL ENGINE The I-shift gearchanging program is tailored for the power output and performance profile of each individual Volvo engine, whether Volvo D9 or D12. You are guaranteed perfect driveability and consistent fuel consumption. The I-shift gearbox also has lower frictional losses than its manual counterparts, which in turn contributes to lower fuel consumption.

GEARTRONIC Do you haul a 44–60 tonne gross combination weight on good roads and want comfortable, safe driving? If so, the choice is simple: Geartronic, an automatic gearchanging system based on Volvo’s 14-speed manual gearboxes – VT2214B and VT2514B. In addition, you can change gears manually whenever you want.
WIDE GEAR SPAN Geartronic allows you to exploit the manual gearbox’s considerable freedom of choice and flexibility. You have access to 14 forward gears, including two crawler gears that ensure smooth starts with high train weights. The entire gearchanging process is automatic and is controlled extremely precisely by an electronic control unit that communicates with the vehicle’s various systems. The electronic unit, the solenoid valves and operating cylinder are built into an aluminium housing above the gearbox. The gearchanging program, current gear and available ratios are all shown in the driver’s display.
SWIFT AND SECURE GEARCHANGES Geartronic changes gear quickly and smoothly due to Volvo’s dual synchromesh system. The gear lever is marked with the same positions as in a manual gearbox. In addition you can select automatic gearchanging, reducing driver stress. There is a “Hold” function allowing you to remain in the selected gear for a short while, for example you would not want the system to change up just before you reach the brow of a hill or when you are rounding a sharp corner. With the rocker switch on the side of the gear lever, you can fine-tune your progress by choosing a higher or lower gear.
CHANGE GEARS MANUALLY WHENEVER YOU WANT If you want to maintain control over the gearchanging process you can use the gear lever just as you would on a manual gearbox – with the difference that you do not need to worry about pressing the clutch pedal since there isn’t one. The electronic system takes care of everything. Just move the gear lever gently to each respective gear position. Even when you drive in automatic mode, you can at any time take over and change gears manually.
The gear lever allows you to change gears manually at any time.
The driver’s display keeps you constantly updated on the gearchanging function.
ECONOMY OR PERFORMANCE No matter which gearchanging method or driving mode you use, the electronic system ensures that the gearchanging pattern is always gentle and that engine revs and other parameters are within the permitted limits. If you want to save fuel, drive in E mode, which utilises the engine’s Economy band in an optimum way. If the terrain is very hilly and you need maximum power, you can engage the P mode, which utilises the engine’s upper rev band before changing gears.
EXTRA-SAFE With the Volvo Engine Brake (VEB) or Volvo’s hydraulic compact retarder, you can control braking power with a stalk beside the steering wheel. If you need quick access to maximum braking effect, there is a stalk setting where the electronic system changes down – thus raising engine revs – to maximise the braking effect of the auxiliary brake. This technology naturally extends the service life of the truck’s foundation brakes.

MANUAL GEARBOXES Now it is easier and more convenient than ever to change gears manually. The new Volvo FH and FM are available with a complete series of range-change and splitter gearboxes with 8, 9 or 14 forward gears. All are equipped with Volvo’s patented “servo synchro” system and an entirely new gearchange control.
EXCELLENT DRIVEABILITY Volvo’s range-change and splitter gearboxes are compact, lightweight units. Precise and smooth gearchanges characterise Volvo’s gearboxes, which feature few base gear positions but many ratios thanks to the range-change and splitter functions. In short, they’re all about giving you good driveability. The gears are well-matched and both the rangechange and splitter gears are handled conveniently via rocker switches on the gear lever. With 9 and 14 forward gears you have one or two crawler gears respectively so you can always
start off securely and smoothly with high gross combination weights. At the same time, the high ratio span permits a fast rear axle ratio for fuel-efficient cruising. There is also a comprehensive series of dependable gearbox-driven power take-offs to choose from.
SAFER AND MORE CONVENIENT In the new Volvo FH and FM, the link-rod system has been replaced with a smooth, light-action cable link. Gearchanging comfort is significantly improved. Lever movement is shorter and more distinct, and
8 • Manual gearboxes
VT1708B VT2009B VT2214B VTO2214B VT2514B VTO2514B
vibration and noise from the gear lever are a thing of the past. Together with Volvo’s servo synchro system, which has been further improved, and a smooth, light action clutch, you will note that gearchanging is both lighter and more convenient than before. All the rangechange and splitter gearboxes now have the latest smart servo synchro system. The synchromesh functions at the instant the gears shift automatically converts radial torque into an axial force, which in turn assists the gear selection, therefore reducing the amount of driver effort – in short, servo assistance. This technology reduces gearchanging forces by up to 50%. The gearbox is monitored by an electronic system that ensures that the gearchanging function always operates within permitted rev ranges and prevents unintentional gearchanges.

LONG SERVICE LIFE The gearboxes for the new Volvo FH and FM are the result of more than 35 years of experience with rangechange and splitter gearboxes. They are developed down to the smallest detail to ensure high operating reliability and long service life. All the gears in the base unit are helical (which means many teeth are engaged at the same time) and they are case-hardened for high strength. The shafts are robustly dimensioned and they feature conical roller bearings which are constantly cooled and lubricated by the forced lubrication system. The oil is cleaned by a full-flow oil filter, and you can specify an optional oil cooler if operating and climate conditions are particularly tough.

You can choose automatic or manual gearchanging and prioritise economy or performance.
The gearchanging function is shown continuously in the driver’s display.
You can determine the required braking effect with the stalk.
POWERTRONIC If your operations involve tough conditions with many and frequent stops and starts, Volvo’s unique Powertronic automatic transmission is the right choice. Gearchanges are electronically governed and there is a choice between 5 or 6 gears. Powertronic offers superb starting and driving properties on poor surfaces. You can specify a primary retarder (option) which provides 300–450 kW in continuous braking effect, even at low speeds.
CONSIDERABLE FLEXIBILITY
SUPERIOR OFF-ROAD ABILITY
Powertronic comes into its own in heavy construction operations and refuse operations. Gearchanges are normally handled entirely electronically. If you do not want the electronic system to perform the gearchanges, you can change gears manually via a button on the gear selector. There are also two driving modes to choose between – Performance (P) and Economy (E) – and you can at any time use a “kickdown” function which gives you access to maximum power via the accelerator. The driver’s display gives you total information about the system. You can see at all times which gear is currently selected, which driving mode is active and which gears are currently available. Powertronic also has a clutch-independent multiplate power take-off that provides 100 kW or 650 Nm.
Powertronic has a hydraulic torque convertor which doubles torque in a short space of time and provides smooth and gentle starts. Gearchanges take place quickly, without any interruption in power delivery to the driven wheels, thanks to the use of hydraulic multi-plate torque convertor. You can quickly accelerate up to speed even if there is considerable rolling resistance, and you can take steep gradients at high speed. Nor is it a problem to manoeuvre with extreme precision both forwards and in reverse at low speed, or to reverse quickly over long stretches.
SAFE PROGRESS Automatic transmission means that progress is smoother. Secure starts and gearchanges without any interruption in power delivery also remove a large element of stress from the driver. If you choose the primary retarder, you always have access to high braking effect, which can be regulated via a stalk

beside the steering wheel. You can choose between various levels of braking, or you can let the retarder engage automatically together with the wheel braking system whenever you press the brake pedal. For maximum braking effect, the electronic system can automatically change down to raise engine revs and thus boost braking effect. The system also has an automatic setting that allows you to maintain a constant speed when driving downhill. Set the retarder in automatic mode and the electronic system will then take over and adjust braking effect to suit the selected speed and the gradient.
LOWER RUNNING COSTS The electronic system constantly ensures that all the functions operate optimally and keep within the relevant limits. There is no risk of over-revving, overloading or excessive temperatures. You always start off gently and gearchanges take place without any disruption in power delivery to the wheels. This means that the powertrain is never subjected to shock loads, and that wear on all the powertrain components is minimised – as are your repair costs. To save fuel, you should utilise the Economy Program (E) as often as possible. Here, all gearchanges take place based on the engine’s most economical rev range. All the gears feature automatic direct lock-up, which in turn promotes less frictional losses. If you have selected the primary retarder, you will also considerably extend the service life of your wheel brakes.

HYDRAULIC COMPACT RETARDER – VR3250
ALWAYS TOP SAFETY If you run normal long-haul operations, the retarder system will handle 80–85% of all braking and helps ensure that the wheel brakes maintain a low temperature. This in turn means you have access to the wheel braking system’s maximum braking capacity if you should need it in a critical situation. You can use maximum effect, 600 kW, for 15–20 seconds. Braking effect declines gradually as temperature rises, down to about 400 kW which you can utilise continuously. The retarder system responds very swiftly. You have access to 90% of braking effect within 0.5 seconds. Activation is very smooth and gentle since compressed air is utilised to regulate the amount of fluid in the retarder. With the stalk in automatic mode, you can engage automatic speed control when driving on a downhill gradient. If you have specified one of Volvo’s automatic gearchanging systems – I-shift or Geartronic – you can use their brake function and obtain maximum braking effect since the electronic system will change down as required.
With Volvo’s electronically controlled compact retarder, you always have access to high braking effect – 400–600 kW. This results in more secure driving while at the same time allowing you to increase average speeds. You can set the retarder system to activate when you press the brake pedal and you can, for instance, allow the retarder to automatically modify the braking effect to suit the speed you want to maintain on a downhill gradient. FLEXIBLE USE The retarder and the engine’s exhaust brake interact to together to provide a high braking effect. The system is also fully integrated with the truck’s wheel braking system. A stalk beside the steering wheel allows you to select which system you want to use. The retarder can be controlled by the stalk or can be set to activate everytime you press the brake pedal. On the driver’s display, you can see which retarder system function is currently in operation.
LOWER BRAKING SYSTEM COSTS Used correctly, the retarder will take care of most braking. Both the brake pads/linings and discs/drums will last far longer. There is also a limit on thermal fluctuation in the wheel brakes, which lowers wear since high temperature means faster brake lining and pad wear. What it all comes down to is that your running costs are lower with Volvo’s retarder system.
Braking effect and function are conveniently controlled with the stalk.

LONG SERVICE INTERVALS With Volvo’s special oil, you only need to change the gearbox oil and oil filter every 3 years or after max. 400,000 km. This applies to I-shift, Geartronic and all manual gearboxes.
LUBRICATION-FREE A gear-driven auxillary power steering pump (8×2/8×4) is available for all gearboxes. Crosstooth flanges in the power transmission permit the transfer of high loads and torque.
All the propshaft universal joints and support bearings are lubricationfree owing to the use of modern, high quality grease and effective seals and encapsulation to keep out dirt and water. High-pressure truck washes are no problem at all.
STURDY PROPSHAFTS Cross-tooth flanges are used on all flanges in the propshaft links. This design provides immense strength and permits high torque. In addition, fitting and removing the propshafts is quicker. In principle, this design features a male and female coupling with sturdy teeth that engage one another in deep grooves for secure grip.

PROFITABILITY BENEFITS OF VOLVO’S GEARBOXES, RETARDER SYSTEMS AND POWER TAKE-OFFS HIGH PRODUCTIVITY
HIGH DRIVER EFFICIENCY
■ Broad range of gearboxes – six manual gearboxes, two with an automatic gearchanging system and one fully automatic transmission (Powertronic). ■ Comprehensive range of gearbox-mounted power take-offs for driving up to three applications. ■ Clutch-independent power take-offs: Volvo D9, D12, Powertronic, flywheel-based power take-off (FM). ■ I-shift – entirely new transmission – and Geartronic with automatic gearchanging system contribute to high average speed. ■ Powertronic fully automatic transmission for gearchanges without any interruption in power delivery – good “get-youthere” ability. ■ Manual gearboxes with crawler gears for secure starts and wide ratio span. ■ Primary retarder for Powertronic and hydraulic compact retarder contribute to high average speed.
■ Automatic transmission or automatic gearchanging for comfortable and safe driving. ■ I-shift with gear lever conveniently attached to the driver’s seat. ■ Intelligent interaction between auxiliary brake and wheel brakes. Operation via a stalk beside the steering wheel or via the brake pedal. ■ Auxiliary brake permits automatic cruise control on downhill gradients. ■ Brake setting (stalk) which provides automatic downchanges and max. effect from the auxiliary brake. ■ Driver’s display provides ongoing information about gearchanging and braking functions, etc. ■ Easy-change manual gearboxes featuring Volvo’s patented servo synchro system and a new cable-operated gearbox linkage.
MAXIMUM UPTIME
LOW OPERATING COSTS
■ Electronic control and monitoring of gearchanging functions ensure high operating reliability. ■ Volvo-developed PC-program for programming and fault-tracing. ■ I-shift, Geartronic and Powertronic with back-up system that allows the truck to proceed to the service workshop should anything untoward occur. ■ Long oil-change intervals – every 3 years or max. 400,000 km. ■ Lubrication-free propshaft universal joints and support bearings.
