How do you shift an Allison trans?

Shifting an Allison transmission typically involves using either a gear selector or a shift lever, depending on the model. For automatic versions, simply move the selector from "Park" to "Drive" or "Reverse" as needed, ensuring the vehicle is at a complete stop before changing gears. In manual mode, you can select gears by moving the lever to the desired position, allowing for more control over shifting. Always refer to the vehicle's owner manual for specific instructions related to your model.
