I-Shift software packages

I-Shift construction gear changing software (TP-CON)

TP-CON adapts the gearbox’s function to the specific conditions in the construction segment. The software package includes functions that aid manoeuvrability when starting off from standstill, in manoeuvring and when driving at low speed. This software can also handle tougher road conditions.

Heavy duty transport (TP-HD)

TP-HD optimises I-Shift for heavy duty transport with high gross combination weights (>85 tonnes). Regardless of the gross combination weight, the driver can always optimise drivability by selecting or deactivating the heavy duty mode, and activating the long haul mode. The functions in the software package also offer
benefits for trucks hauling multiple trailers.

I-Shift functions explained

Basic Shift Strategy
Automatic selection of the right starting ratio (1st – 6th gear). The choice of starting gear is influenced by gross weight and road gradient.

Performance Shift
Gives faster and gentler changes through intelligent utilisation of the engine brake, the vehicle’s clutch and a special transmission brake.

Basic Gear Selection Adjustment
Makes it possible to adjust gear selection via the gear lever’s buttons during engine braking in automatic mode.

Gearbox Oil Temperature Monitor
Shows the gearbox oil’s temperature in the information display.

Enhanced Shift Strategy
By interacting with EBS and ECS, starting and close-quarter manoeuvring are made easier. Maximises the VEB/VEB+ braking effect by automatically selecting the right gear, so that the engine operates at high revs. When changing gear during engine braking, the wheel brakes are activated to compensate for loss of braking torque.

Launch Control
Optimises gear selection and EBS functions for manoeuvring at low speeds. Among other things, this also ensures that the Hill Start Aid function is only activated on uphill gradients.

Automatic engagement and disengagement of a freewheel function for the purpose of reducing fuel consumption. I-Roll is used when neither engine power nor engine braking is needed: on flat roads, for instance.

Smart Cruise Control
Interacts with the vehicle’s Brake Cruise and ensures that the auxiliary brakes are not activated unnecessarily. The free-wheel function can thus be utilised to an even greater extent.

Heavy Duty GCW control

Optimises gear selection for high gross combination weights, 85–180




Additional options

Enhanced PTO Functions
Several functions that make power take-off use easier.

Enhanced Gear Selection Adjustment including kick-down
Makes it possible to adjust gear selection via the gear lever’s buttons during start and when driving in automatic mode. The kick-down function selects the right gear for maximum acceleration.

Enhanced performance – Bad roads
Several functions that adjust gearchanging and assist starting and driving in poor road conditions and hilly terrain.


Fully automatic power-shift transmission with torque converter and oil cooler. Changes gears without power loss. Powertronic can be factory-fitted with a power take-off, integrated retarder and emergency power steering pump.


Type Top gear Engine torque (Nm) GCW approval (tonnes)
PT2606 Direct 2600 60

Powertronic, integrated driving programs


Intended for optimal fuel economy. Gear changes take place in the most economical rev range.


Used when there's a need for added engine power output. Changes up and down at higher engine revs.

Manual gearboxes

14-speed splitter and range manual gearbox with two crawler gears and twelve synchronised forward gears, plus four reverse gears. Cable operation give short and distinct gearshift strokes and eliminates vibrations in the gearshift knob. Patented synchromesh with servo function means low gearchanging forces. The gearboxes can be fitted with a compact retarder, power take-off, emergency power steering pump and oil cooler.
