What Causes the Jerking During Low-Speed Gear Shifts in the Atenza?
2 Answers
The jerking during low-speed gear shifts in the Atenza is caused by clutch failure. Below is a detailed introduction to the Atenza:1. Configuration: The new vehicle comes standard with features such as the Smart Idling Stop System and Brake Energy Regeneration System. The Atenza 2.5L model accelerates from 0 to 100 km/h in just 8.3 seconds, with a combined fuel consumption as low as 6.9 liters per 100 km, while the 2.0L model achieves a combined fuel consumption of only 6.3 liters per 100 km.2. Exterior Design: The car adopts Mazda's KODO design philosophy, featuring a U-shaped front grille paired with LED headlights for a more sporty appearance. The new model introduces an 11-speaker sound system. Compared to the previous-generation Mazda6, the Atenza's wheelbase has been increased by 112 mm, providing more spacious rear seating. The Atenza utilizes the SKYACTIV-Chassis technology, equipped with a high-performance MacPherson strut front suspension and a multi-link independent rear suspension. Through structural optimization, it achieves both weight reduction and increased rigidity.
Last time I drove my friend's Atenza, I noticed this issue. Low-speed gear shift jerks are mostly due to the transmission fluid needing replacement. Although the Skyactiv 6AT is smart, when the fluid deteriorates, the shift speed can't keep up with the computer's commands. Clogged fine oil passages in the valve body can also cause unstable oil pressure, especially noticeable when the car is cold. Engine mount deterioration is a hidden culprit, transmitting engine vibrations directly into the cabin, making it feel like a kick. Also, some people overlook the calibration of the semi-engagement point. In some older cars, when the transmission's self-learning parameters deviate, the jerk when releasing the throttle at 20km/h is particularly jarring, and a TCU reset at the dealership is needed to fix it.
