Shudder At Low Speed
A shudder or judder when pulling away or at low speed, often like driving over rumble strips, usually comes from the torque converter clutch or dual-clutch gearbox, a worn clutch or a misfire under load.
Normal risk
Have it checked soon, especially if it comes with a gearbox or engine warning.
Short answer · Why does my car shudder at low speed?
Automatic gearboxes lock their torque converter at low speeds to save fuel; worn or contaminated clutch material makes it judder when it engages. Dual-clutch gearboxes judder when their clutches wear or need relearning. Manual cars judder from a worn or oily clutch. A misfire under light load feels similar but usually sets an engine code.
Safe checks you can do
