Hesitation and rough shift when pulling away from a stop

Some drivers notice that this type of 9-speed automatic shifts more firmly or hesitates slightly at low speeds, and manufacturers have released software updates for shift quality on several models. A noticeable thump or delay is still worth checking rather than assuming it is normal.

Things a shop will usually look at: any stored transmission codes (there can be codes without a warning light), whether there are open service bulletins or software updates for your vehicle, the fluid condition and level, and whether the engine and transmission mounts are worn, since worn mounts can turn a normal shift into a thump.

We suggest a test drive with a technician when the car is cold so they can feel what you are describing. A dealer can check for updates and campaigns by VIN. Avoid adding additives to the transmission.
