What Makes I-Shift
So Intelligent?
Teamwork. Integration. Information.
• I-Shift knows the engines’ efficiency map for each engine rating
• Only Volvo can integrate so well.
• Higher level of information
• Result: Maximum intelligence and efficiency
WE TRUST THE TRANSMISSION TO CONTROL THE ENGINE!

E / P Operating Modes
Fuel Economy Mode
• In “E” mode, the transmission will select shift points and
command engine parameters that maximize FUEL
ECONOMY. Shift points are at low RPMs and gears are
skipped to reduce languishing in lower gears.
Performance Mode
• In “P/P+” mode, GRADABILITY is maximized. RPM in each
gear is increased, more gears are taken, and more power is
available. The “P” mode will default back to “E” after a while
when no longer used.
• Even when the Premium Shifter is used, the E/P switch can
be programmed out, if desired, and re-enabled at resale.
Volvo I-Shift (D-Series)
Performance/P+ Additional Features
• Ability to Rock Free
• The I-Shift has the ability to rock the vehicle back and forth to maneuver
out of a stuck situation.
• In most instances, the shifter doesn’t need to be changed between
forward and reverse – simply pump the accelerator.
Volvo I-Shift (D-Series)
P+ Additional Features
• Power Launch
• If the vehicle becomes “really stuck” in sand or very soft soil and is
equipped with the Performance software package, the I-Shift has the
ability to use extra engine torque to get the vehicle moving once again.
Volvo I-Shift (D-Series)
Premium Shifter Additional Features
• Avoid Shifts in Drive Mode
• Delay a downshift by pushing the plus (+) button on the shifter while the
engine rpms are very low – useful when approaching the top of a hill when a
downshift is not desired.
• Delay an upshift by pushing the plus (-) button on the shifter – useful when
driving uphill with poor traction or when approaching a hill where higher
engine rpms are needed for more efficient operation.
Volvo I-Shift (D-Series)
Premium Shifter Additional Features
• Greatest Possible Downshift
• To evoke one large downshift instead of several smaller ones – useful when
approaching a steep hill in off-road conditions when a higher engine speed is
needed.
• The I-Shift uses its grade sensor and GCW calculations to determine the best
gear to select.

Upgradeability
• I-Shift can accommodate upgrades to any
available engine rating without requiring clutch or
transmission changes.
• I-Shift can be upgraded from Basic to Premium Shifter at trade-in for higher
residual value.
• I-Shift can be re-rated to any software package.

I-Shift Clutch Package
17” Organic Faced Spring Dampened Clutch
Clutch Warranty
•Normal Duty = 3 years / 300,000 miles / 7,500 hours
•Heavy Duty = 3 years / 250,000 miles / 6,250 hours
•Severe Duty = 1 year / 100,000 miles / 3,250 hours

Accelerator Pedal
With Kick-Down Switch
• Firm Detent Near Bottom
• In “Kickdown” mode, downshifts
occur when possible and
ACCELERATION is maximized
Volvo I-Shift (D-Series)
Idle Driving Mode
Facilitates driving slowly
•
Lets the driver drive at engine idle speed
in any of the lower range gears (1-6)
•
A touch of the throttle (or + button on the Premium
shifter) Increases to the next higher gear
A slight press on the brake pedal (or – button on
the Premium shifter) will downshift to a lower gear
•
•
•
The clutch is not slipped and is only opened when
the vehicle stops
Works well in reverse backing a trailer
Volvo I-Shift (D-Series)
Grade Sensor Allows I-Shift
To “See” What’s Ahead
Informed Technology
• I-Shift has a Grade Sensor, so it knows how steep the grade is and if
it’s changing
• I-Shift continuously monitors the grade, vehicle speed, acceleration,
torque demand, weight, rolling and air resistance
• I-Shift continuously predicts and selects the most efficient utilization of
the engine over the next rolling 30 second period.

Forced Lubrication
• Gear type oil pump
(Similar to engine oil pump)
• Pumps lubricant through
drilled passageways for
superior lubrication
• Lube Oil Filter will remove
any contaminants
• 500,000 mile oil change
intervals with on-highway

I-Shift Application Guidelines
• MAKE TOUGH STARTS IN “P”
•
•
•
•
On-Highway to 143,000 pounds beginning NOW (D16).
VHD flat or partly hilly on-off highway to 110,000 beginning NOW.
Strictly off-road (severe mining, etc.) still should use Allison
As before, no mixers, no refuse. However, 6x4, 8x4, 10x4, 12x4 dump
trucks, 105,500 chip trucks, 105,500 transfer dumps, block trucks, fire
trucks, snowplows, line stripers, vac trucks, etc.

What Does Volvo I-Shift NOT Do?
I-Shift doesn’t get locked in gear if you shut it off in gear by mistake and the air
pressure bleeds down.
• Instead, when you turn off the key with the selector in gear, the
transmission shifts to neutral before it turns off the engine.
I-Shift doesn’t tear up your dock or your ICC bumper backing up.
• Instead, when you back up and touch the brake, it de-clutches rapidly.
I-Shift doesn’t “beep” at you to tell you it won’t shift.
• Instead I-Shift tells you if it CAN shift with arrows in the DID before you try.
I-Shift doesn’t just sit there if you stop while in Manual Mode and try to take off in
too high a gear.
• Instead, a pop-up message tells you to downshift or to put it in “D”.
