  • Why no-lift shifting is not good

    You may have heard the term before: "no-lift shifting." It's the process of foregoing the clutch altogether and simply popping the car into the next gear. Long story short, it's a really bad idea. Jason Fenske of Engineering Explained tells us all about the issues the process causes in a new episode. We'll separate the topics into two categories: no-lift shifting and "power shifting." No-lift shifting is really bad for a pretty straightforward reason. Without using the clutch, the driver is asking the synchronizer to do a job it's not supposed to do. That is, match the wheel speed to the...
