Identification tag
How to identify your I-Shift
The I-Shift has an identification label on the transmission housing showing the model designation, serial number and part number. The model designation indicates torque capacity and whether it is direct drive or overdrive.
The truck VIN is equally important because the I-Shift is integrated with Volvo's engine and vehicle electronics. Volvo's build records tied to the VIN show the original transmission specification.
01Automated manual, not automatic
The I-Shift is a gearbox with an automated clutch and computer-controlled shifting. It has no torque converter, which makes it different from an Allison automatic.
02Direct drive, overdrive and crawler gears
I-Shift units come in direct-drive and overdrive versions, and crawler-gear versions add extra low ratios for vocational and heavy-haul work. Changing versions affects cruise RPM and low-speed performance, so match the label.
03Control unit, software and harness
The transmission control unit is mounted on the I-Shift and must work with the truck's software. A replacement often needs software and parameter programming with Volvo dealer tools. Confirm connectors and harness versions match your truck.
04PTO and clutch
If the truck uses a PTO, check that the replacement is set up for it. Note whether you need the clutch or clutch actuator with the transmission.
05Core and exchange
Core charges or exchange terms may apply depending on the supplier. If they do, they are confirmed on your quote before you commit, along with availability and freight.

FAQ
Volvo I-Shift questions
Is the Volvo I-Shift an automatic?
No. It is an automated manual transmission with an automated clutch. It does not use a torque converter.
Is the I-Shift the same as the Mack mDRIVE?
Volvo and Mack are both part of the Volvo Group and the mDRIVE is closely related to the I-Shift. Controls, software and parts can still differ, so we search by the exact unit your truck uses.
Will a used I-Shift need programming?
Usually some programming is required so the transmission works with the truck's software. A Volvo dealer or properly equipped shop can do this.
What does a crawler-gear I-Shift do?
Crawler versions add extra low gears for very slow, controlled movement and heavy starts, common in vocational and heavy-haul work.
