Acceleration from a stop causes car to shudder and shake violently (with loud hammering sound) during low speeds for a maximum of 3 seconds, then everything is fine until the car stops and accelerates again. On some days, there is little to no shuddering/shaking at all and the car just occasionally jerks forward when I lightly press the accelerator, on other days the shaking/shuddering is almost always there, always when accelerating after a stop. Observed that shaking nearly always happens when automatic transmission shifts from gear 1 to gear 2, however all other gear shifts are fine even from gear 2 to gear 1. There is no strange smell or clicking noises. Recently changed oil/filter and air filter. Any help would be great thanks 🙂
