Tractorheads with automated gearbox
The automated manual transmission (AMT) is now the standard in the European tractorhead market, representing over 90% of new registrations. Unlike a conventional automatic gearbox (with torque converter, as in a car), an AMT is a robotised manual gearbox: it uses a conventional dry clutch and mechanical gears, but gear changes are executed by an electrohydraulic system controlled by an electronic control unit, eliminating the clutch pedal.
Automated vs automatic vs manual
It is important to distinguish between the three types of transmission available in tractorheads:
- Manual: Mechanical gearbox with clutch pedal and gear lever. The driver selects each gear. Typically 12 or 16 speeds (ZF Ecosplit, Eaton Fuller). Still preferred by some veteran drivers and in markets such as Eastern Europe.
- Automated (AMT): Robotised manual without clutch pedal. The electronic system selects the optimal gear based on speed, load, gradient and route profile. The dominant type in Western Europe since 2015. Examples: I-Shift, Opticruise, TraXon, PowerShift, Optidriver.
- Automatic (torque converter): With hydrodynamic torque converter. Very rare in European heavy trucks, more common in city buses and North American trucks. The Allison 4000 series is the only significant option in Europe, used mainly in fire engines and special applications.
Leading automated transmissions
Each manufacturer has developed its own automated transmission or uses the ZF TraXon:
- Volvo I-Shift: Introduced in 2001, it was the first AMT on the market and remains the benchmark. 12 speeds with Economy, Performance, Off-road and slow manoeuvring modes. The I-Shift Dual Clutch version (2014) was the first dual-clutch transmission for trucks, eliminating torque interruption during shifts. Available with Crawler Gears (2 ultra-slow speeds for precision manoeuvring).
- Scania Opticruise: 12 speeds with GRS (Gearbox Range Splitter) for 24 effective ratios. Famous for its shift speed and smoothness. Scania was the first manufacturer to offer factory Crawler Gears for manoeuvring at speeds below 1 km/h. Shift software is updated with each service revision to optimise performance.
- ZF TraXon: Independent transmission used by DAF, MAN and Iveco. 12 or 16 speeds. The PreVision GPS version anticipates shifts based on topography. The ZF TraXon Hybrid adds an integrated 120 kW electric motor for plug-in hybrid functionality.
- Mercedes PowerShift 3: Developed in-house by Daimler. 12 speeds with Predictive Powertrain Control (PPC) using GPS and 3D terrain data to optimise gears and speed over a 3 km horizon. Compatible with the Actros Active Drive Assist semi-autonomous driving.
- Renault Optidriver: Based on Volvo technology (AT2612). 12 speeds with Optivision (GPS prediction) and Eco-roll (automatic neutral on gentle descents to reduce consumption). The Optifuel system provides real-time driver coaching.
- Iveco HI-TRONIX: Iveco's own development. 12 speeds with consumption-optimised shift algorithms. Includes eco-roll mode and rocking mode to free the vehicle on soft ground by automatically alternating forward and reverse.
Advantages of automated transmission
The reasons why AMT has displaced manual gearboxes in Europe are multiple:
- Fuel savings: Between 3% and 5% average reduction compared to manual driving. GPS-predictive systems (PPC, Optivision, PreVision) add an additional 2-3% savings by anticipating shifts based on terrain.
- Fatigue reduction: On a 600 km journey, a driver with a manual gearbox makes between 1,500 and 2,000 gear changes. With AMT, zero. This significantly reduces muscular fatigue and cognitive load, especially in dense urban traffic.
- Lower maintenance costs: The clutch lasts longer because shifts are always executed at the optimal engine speed. Typical clutch life with AMT is 500,000-800,000 km versus 200,000-400,000 km with manual.
- Multi-driver fleets: In fleets where several drivers share the same vehicle, AMT ensures a uniform driving style, preventing clutch abuse and incorrect shifts that shorten powertrain life.
- Driver recruitment: The shortage of professional drivers in Europe makes AMT a requirement to attract new drivers, many of whom have never driven with a manual clutch.
What to check on the automated gearbox when buying used
Before buying a tractor unit with an automated gearbox, take a road test and check that shifts are fast and smooth, with no jerks, slipping or delays when engaging. Connect the brand diagnostics (VOCOM on Volvo, SDP3 on Scania, ZF-Testman on TraXon) to rule out stored clutch or actuator faults. An AMT's dry clutch lasts 500,000-800,000 km, but a clutch actuator or mechatronics unit can cost 1,500-3,000 € if they fail. At Coatrucks we test the gearbox on every tractor unit and record it in the documented inspection.
Which automated gearbox to choose for your operation
For long haul with relief, GPS-predictive gearboxes (Mercedes PPC, Renault Optivision, ZF PreVision) extract the maximum fuel savings. The Volvo I-Shift is the benchmark for smoothness and reliability, and its Dual Clutch version eliminates torque interruption. The Scania Opticruise stands out for shift speed. For precision manoeuvring (lowbed, site work) look for versions with Crawler Gears. All are reliable if well maintained; at Coatrucks we advise based on your routes and cargo type before you commit.

Frequently asked questions
What is the difference between automated and automatic gearbox in a truck?
The automated gearbox (AMT) is a robotised manual with a dry clutch: the electronic system shifts gears without a clutch pedal, and it is the standard on over 90% of European tractor units (I-Shift, Opticruise, TraXon). The automatic with torque converter (Allison) is very rare in European heavy trucks and reserved for fire engines or special applications. When we say automatic tractor unit we almost always mean an AMT. At Coatrucks all we sell are AMT.How much fuel does a tractor unit with automated gearbox save?
An AMT saves between 3% and 5% on average versus manual driving, because it always shifts at the optimal speed. GPS-predictive versions (Mercedes PPC, Renault Optivision, ZF PreVision) add an extra 2-3% by anticipating gears based on relief. For a haulier covering 130,000 km/year, that saving means thousands of euros a year in fuel. It is one of the reasons AMT has displaced manual in Europe.Is a second-hand I-Shift, Opticruise or TraXon gearbox reliable?
Yes, all three are very reliable, mature gearboxes. An AMT's dry clutch lasts 500,000-800,000 km, far more than manual, because it always shifts at the optimal point. What you should check when buying used is the clutch actuator and mechatronics, whose repair costs 1,500-3,000 € if they fail. With a clean brand diagnosis, an automated tractor unit with 600,000-800,000 km is a safe buy. At Coatrucks we test the gearbox on every unit.Which automated gearbox is best: I-Shift, Opticruise, PowerShift or TraXon?
The Volvo I-Shift is the benchmark for smoothness and reliability, and its Dual Clutch version eliminates torque interruption. The Scania Opticruise stands out for speed. The Mercedes PowerShift 3 with PPC is among the best at GPS prediction. The ZF TraXon (DAF, MAN, Iveco) is robust and versatile. All are excellent; the choice usually follows the truck brand. At Coatrucks we advise based on your routes and cargo type.How do I know if a used tractor unit's automated gearbox is fine?
On a road test shifts should be fast and smooth, with no jerks, slipping or delays when engaging a gear. It is wise to connect the brand diagnostics (VOCOM, SDP3, ZF-Testman) to rule out stored clutch or actuator faults. You should also check there are no dashboard warnings. At Coatrucks we verify the gearbox operation on every tractor unit and record it in the documented inspection we deliver with the vehicle.Is it worth paying more for an automatic tractor unit over a manual?
Yes, in the vast majority of cases. The premium is recovered through 3-5% fuel savings, lower clutch wear (it lasts two to three times longer), reduced driver fatigue and much better resale: today almost nobody wants a manual tractor unit in Western Europe. It also makes hiring young drivers easier. Only in very specific markets is manual still of interest. At Coatrucks practically all long-distance stock is automated.Can I import an automatic tractor unit from Europe with Coatrucks?
Yes. Practically all the tractor units we import from Germany, the Netherlands, France or Sweden have an automated gearbox as standard (I-Shift, Opticruise, TraXon, PowerShift, Optidriver). We handle transport, reduced homologation in Spain (technical sheet with COC, 24-48 h) and registration fees, with a fixed quote before we start. As an intra-EU transaction, VAT is 0% via VIES if your company is on the ROI register. Typical timeline: 7-15 days.
