Let’s take a brief look at the specifications:
We’ll be talking about three different models of I-Shift. All have 12 forward speeds. For EPA’10, these transmissions will be the “D” version
So the way we define it as shown here is that the first two models are matched to the Volvo D11 and D13, while the third model on the right is matched to the D16.
The Volvo I-Shift transmission has the highest input torque capacity of any transmission sold in North America today. In addition, it’s the only transmission which can be used behind Volvo’s 700 HP D16 Euro V engine, with 2323 lb-ft (3150 N-m) torque rating. No matter the model of the I-Shift transmission, the same robust internal gears are used and the transmission will always meet or exceed the torque rating of the engine with which it is paired.
The overall ratio is ample for all conditions. And all I-Shifts are extremely lightweight, as you see here, even less than 600 pounds for the D11/D13 models..

5. I-Shift Weight Benefits
D13 + I-Shift = 3262 lbs
ISX + Ultrashift PLUS = 3879 lbs
Speaking of weight – did you know that compared to the lightest Ultrashift PLUS LAS, I-Shift is lbs. lighter, including the weight for clutch packages.
This is extremely important in today’s market, especially with installation of the additional EPA’10 components.
D13 + I-Shift = 3262 lbs
ISX + Ultrashift PLUS = 3879 lbs
That’s a 600+ lb weight savings! An additional 600 lbs of cargo on each trip can add pretty quickly to a company’s bottom line.
712 – 726 lbs.
915 – 995 lbs.

6. What Makes I-Shift So Intelligent?
Exclusive Feature
I-Shift
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!
I mentioned intelligence in one of the earlier slides......so, what Makes I-Shift so intelligent? – Teamwork. Integration. Information.
Volvo I-Shift transmissions have been fully designed and engineered by Volvo – by the same overall Engineering Department that engineers Volvo engines. Thus the engine and transmission can be truly designed together as one. They speak the same language, using proprietary protocols, are designed to meet the same project goals and timing, and are designed with mutually agreed upon engineering concepts and strategies. For example, the I-Shift transmission is given significant authority to control the engine under various conditions.
I-Shift takes customer values to an unprecedented level. It features very smooth operation together with many features that improve drivability, safety and fuel economy. Only Volvo is so well positioned to integrate the engine, transmission, and vehicle together.
Result: Maximum intelligence and efficiency
This integration allows Volvo to put the customer first, in a way that no other Powertrain can!

There has been another AMT (Eaton Ultrashift Plus) which has recently entered the market and attempted to copy the I-Shift in many ways. But, there are still features exclusive to the I-Shift which makes it the leader in AMT technology.
Here’s a list of some of these exclusive features, which we will discuss in more detail in the following slides.

8. Six (6) Software Feature Packages
Exclusive Feature
I-Shift
Here is the overall I-Shift Software Features package chart –
We won’t go into detail here, but…
“Gentle-Shift” is a new software package that has been added for 2010 with the D-Series I-Shift.
While not for everybody, “Gentle-Shift” emphasizes very gentle starts and gearchanges over performance.
It will be useful in tankers, livestock hauling, motorcoaches, team drivers, etc.
Also available “unpublished” are the Basic and Enhanced Basic offering. Using the Fuel Economy package offers more flexibility based of the selectable parameters and allows us to simplify the offering a little. However, they are still available if desired.
More features and greater flexibility than any other automated manual transmission due to these six feature packages that gives you the flexibility needed to tailor the transmission to every need. Can easily be recalibrated if the operation changes or for resale.

12. Exclusive Feature I-Shift 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.
In “E” mode, the transmission will select shift-points and command engine parameters maximizing FUEL ECONOMY. The vehicle will actually achieve cruising speed faster because of the skipped shifts!
In “P/P+” mode, GRADABILITY is maximized. NOTE: The P+ mode is only available with the Performance software package.
In “KD” (kick-down) mode, ACCELERATION is maximized.
Only Volvo has Fuel Economy, Performance and KD in the same Transmission.
This enhances residual value when the truck enters it’s second life.

13. Performance/P+ Additional Features
Exclusive Feature
I-Shift
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.
As mentioned in the previous slide, Performance/P+ mode maximizes power and gradeability. Here are a few other features that are unique to the Volvo I-Shift transmission.
Ability to Rock Free - A combination of carefully pressing and releasing the accelerator, to ease the vehicle forward or backwards, will produce the rocking motion to elongate the wheel tracks which have caused the vehicle to become stuck. To utilize this feature, take the following steps:
Engage differential locks
Turn off traction control
Select Performance/P+ mode of the I-Shift
Move the gear selector to the M-Manual position, 1st gear, or the 1st reverse gear
Carefully press accelerator pedal up and down with a smooth pumping action

14. P+ Additional Features
Exclusive Feature
I-Shift
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.
I know this vehicle pictured is an exaggeration, but let’s say you get the vehicle “really stuck” and are unable to get it moving again by trying to rock it free. That’s where the Power Launch feature comes in. Selection of this feature allows you to use full engine torque to get the vehicle moving again.
Engage as follows:
Engage differential locks
Select P+ mode of the I-Shift
Move the gear selector to the D or M position, 1st gear, or the 1st reverse gear
Push and hold the minus (-) button on the gear selector
Completely depress the accelerator – the engine will rise to 1300 rpm
Release the minus (-) button and the clutch is engaged, launching the vehicle free

15. Premium Shifter Additional Features
Exclusive Feature
I-Shift
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.
To avoid the I-Shift transmission downshifting when in Drive (D) mode, push the plus (+) button on the gear selector while the engine rpms are very low. This could be used approaching the top of a hill when a downshift is not desired by the driver.
To avoid the I-Shift transmission up-shifting when in Drive (D) mode, push the minus (-) button on the gear selector. This could be when driving uphill with poor traction or when approaching a hill where higher engine rpms are needed for more efficient operation.

16. Premium Shifter Additional Features
Exclusive Feature
I-Shift
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.
Push and hold the minus (-) button and change the gear selector from Drive (D) to Manual (M) mode.
Release the minus (-) button.
This gives a large downshift for the purpose of immediately getting a high engine speed in the vehicle, for instance when approaching a steep hill in off-road conditions.
The I-Shift uses its grade sensor and GCW calculations to determine the best gear to select.

17. Exclusive Feature I-Shift Driver Interface Volvo “DID”
Selector Position
Present Gear
Possible Gears Up & Down
Economy / Performance Mode
If Eco-Roll is enabled
Engine Brake Selection
The I-Shift transmission communicates through the Driver Information Display (DID) in the instrument cluster. All of the needed information is right in front of the driver in an easily readable format. Information displayed is as follows:
Gear selector position
Present gear
Available gears – up or down
Economy or Performance mode
Engine Brake position
If Eco-Roll enabled
The I-Shift lets the driver know the number of steps that can be taken up or down based on present conditions, BEFORE the shift is attempted, not an audible signal to indicate the shift has failed AFTER it has been attempted as with Eaton automated transmissions

18. Integrated Engine Brake Interface
Exclusive Feature
I-Shift
Engine Cruise Control, Engine Brake, & Transmission Integrated Together for Seamless Performance
Off
“A” – Automatic
Brake Cruise Control Enabled
1,2,3 – Manual I-VEB Engine Brake Control
“B” – I-Shift Brake Program Shifts Down for Maximum Retardation
Plus / Minus switch on end for Brake Cruise Control function
I-Shift is perfectly integrated into the Volvo Intelligent Engine Brake (I-VEB) control.
In the ‘A’ position, ‘Brake Blending’ occurs as the I-VEB is operated at 50% level with the application of the footbrake.
Positions 1, 2, and 3 operate the I-VEB at 40%, 70%, or 100%.
When the Brake Mode (B) is activated, the I-VEB comes on 100% and the transmission automatically downshifts to maximize the performance of the engine brake. I-Shift will continuously downshift in Brake mode as the speed decreases in order to maintain maximum retardation. The function then becomes less aggressive in the lower six gears to protect the driveline and improve comfort.

19. Exclusive Feature I-Shift 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.
Upgradeability and flexibility
With I-Shift you avoid all the fuss when it’s time to upgrade Power and Torque.
The clutch and transmission can handle any of the available engine ratings from the lowest to the highest in any engine displacement.
Whether you have Volvo D11, D13, or D16, you can upgrade the engine to its highest rating without needing to modify clutch or transmission.
You can upgrade from Basic to Premium version within the same gearbox. This gives maximum flexibility and resale value for any vehicle and application.
It makes I-Shift a perfect option for dealer stock vehicles.

20. I-Shift Clutch Package
Exclusive Feature
I-Shift
17” Organic Faced Spring Dampened Clutch
Smooth Clutch Engagement
Clutch – The Volvo Sachs 17” clutch assembly is designed for and precisely matched to the Volvo I-Shift application. Critical to the functionality of an automated mechanical transmission, it features a single-plate design with spring-cushioned organic friction facings that ensures drag-free synchronization during gear shifts and the smoothest possible clutch engagement. The combination of these non-aggressive facings and I-Shift’s ability to minimize heat during clutch engagement results in excellent clutch life and reduced Flywheel wear compared to cerametallic facing clutches.
Clutch Actuator – The ZF Sachs “ConAct” clutch actuator provides the Volvo I-Shift with numerous advantages over competitor AMT’s. The lighter-weight and maintenance free actuator is a completely pneumatic device which is electronically controlled by the I-Shift. Combining the functions of numerous components of alternative release systems into a single integrated unit, the wear points and resulting inaccuracies of operation are virtually eliminated. The result is smooth automated transmission shifts over the entire lifetime of I-Shift.
**Anyone who has driven an I-Shift equipped vehicle can attest to the smooth clutch engagement.
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

21. Exclusive Feature I-Shift Accelerator Pedal With Kick-Down Switch
Firm Detent Near Bottom
In “Kickdown” mode, downshifts occur when possible and ACCELERATION is maximized
The accelerator pedal with I-shift features a Kick-Down Mode, with an appropriate detent. Pressing it causes the I-Shift to aim for MAXIMUM ACCELERATION.
Using Kick-Down Mode will:
- Change down a gear if it improves acceleration
- Make the engine operate in it’s peak power window
- Start in a lower gear
The Kick-Down Mode is enabled with some of the premium software packages, as we will describe.
ONLY I-SHIFT COMES WITH A KICKDOWN SWITCH

22. 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
Idle Driving Mode
When traffic jams up on the Interstate, there’s nothing to do but move along slowly in line when you can.
The I-Shift utilizes the Idle Driving mode, which is engaged by the driver removing their foot from the accelerator and allowing the vehicle to idle along. The transmission automatically selects the gear which best suits the speed. The vehicle speed can be adjusted without the accelerator by using the plus (+) or minus (-) buttons on the Premium shifter (if equipped) which slightly raises the engine speed for the transmission to shift up, or slows the vehicle down with a downshift. When the Basic shifter is utilized, slightly pressing the accelerator or brake pedal will change engine speed to facilitate an upshift or downshift.
The Idle Governor also works in reverse and comes very handy when backing a trailer for example.

23. 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.
How Can I-Shift See Into the Future? Intelligent Technology
The transmission knows the engines’ efficiency map for each engine rating - and by continuously monitoring the not just the vehicle speed, acceleration, torque demand, weight, but the GRADE, and the rolling and air resistance, it predicts and selects the most efficient utilization of the engine for the next 30 seconds.
I-Shift has a sensor that tells it what grade it’s on. That helps I-shift determine what gear to start in, where to put the shift points and whether it can skip-shift or not.
Even more: I-Shift looks at how the Grade is changing.
So it can actually predict what the vehicle performance will be in the future.

24. Hill Start Assist – OPTIONAL (Must also spec air ride suspension & Electronic Stability Control)
Brake Pedal Engaged
Hill Start Engaged
Accelerator Pressed
Hill Start Released
Hill Start Assist is a “Nice-To-Have” option for safety and reduction of wear on drivetrain components by eliminating roll-back with I-Shift.
The brakes will remain on for three seconds. During this time, when the driver steps on the accelerator, the truck will begin to move forward with no rollback. It also works when in reverse on a downgrade and allows reversing without any roll-forward.
**This is a feature that the Ultrashift Plus has copied.

25. 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, like all Volvo mechanical transmissions, features a lube oil pump. Like an engine oil pump, it pumps lubricant around through drilled passageways to get it where it’s needed, unlike common splash lubricant designs where all the gears are immersed in the lubricant. The pump also lets us offer a filter. It’s there on the side of the transmission. The filter catches any dirt that may get in to ensure clean lube for long life.

26. PTO’s **Enhanced PTO Features or Multiple PTO’s – Needs a BBM
Clutch dependent PTOs on the Volvo I-Shift are available with multiple power outputs. They can be specified in a variety of configurations with up to three outputs, accommodating direct mount hydraulic pumps (DIN) and flange drive connections. The design is simple and robust, requiring a minimum amount of maintenance. Since the PTO has limited ability for being turned on when the vehicle is moving, due to the clutch being engaged, it may also be an advantage from a safety point of view.
Clutch dependent PTOs are the obvious choice where the vehicle has a manual or AMT transmission and there is no need to use the PTO when the vehicle is in motion.
**Enhanced PTO Features or Multiple PTO’s – Needs a BBM

27. I-Shift PTO Functions Basic – always included with I-Shift

29. 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”.
