When in start and stop traffic when the vehicle is at low speeds below 5 mile an hour. The transmission ds not properly downshift. This causes a severe lag in acceleration when needed in traffic or in Intersections. This delay is a safety issue due to causing a lack of vehicle movement when needed. The vehicle will basically not accelerate for a couple seconds until it decides to downshift. This happens continuously at speeds below 5 mile an hour. If you dont stop completely and pause for a second or two, the transmission will not downshift properly. In traffic, you cannot do this.
