General Motors Electronic Precision Shift Technology
Electronic Precision Shift (EPRS) is a General Motors technology that redesigns a vehicle’s shifting interface to be digital / electronic, thereby removing the physical connection between the shifter and transmission/shift linkage.
Benefits
Electronic Precision Shift improves the driving experience by:
- Reducing noise and vibration
- Delivering smooth, precise and responsive shifting
- Allowing greater use of cabin space
- Reducing weight by eliminating shift gate and shift linkage
In the Cadillac XT5, for example, the greater use of cabin space translates to the “floating” center console that is comprised of a storage space beneath the shifter that isn’t only useful, but also gives the interior a unique design element or feature.

And since the shifting interface is decoupled from the actual mechanism, Electronic Precision Shift can take many forms – be it a joystick, buttons, or a rotary knob.
Types
Current types of EPRS include:
- Joystick-style shifter
- Gear selector on steering wheel stalk
- Push-pull-style button shifter

Usage
The joystick-style shifter might take some getting used to by those accustomed to a traditional shifter. The concept, however, is generally the same as on a traditional shifter: to select a gear, the driver simply depresses a small button on the shifter while moving the joystick to the desired position, as follows:
- Drive is selected by pulling the joystick back
- Neutral is selected by pushing the joystick forward
- Reverse is selected by first pushing the toggle to neutral and then moving it to the left
- Park is selected by a press of the “P” at the top of the joystick
