The valve human body inside the transmission is responsible for directing hydraulic tension to the suitable bands and clutches. It receives pressurized fluid from the most crucial pump and contains numerous spring-loaded valves, Check out balls, and servo pistons. In older automatic transmissions, the valves utilize the pump strain and also the tension from a centrifugal governor to the output side (and other inputs, for example throttle posture or the driver locking out the upper gears) to manage which ratio is selected. Because the motor vehicle and engine alter pace, the difference between the pressures modifications, triggering unique sets of valves to open up and shut.
Sekiranya anda terus menukar equipment P, tuas parkir atau parking pawl akan berkait untuk menghalang kereta daripada bergerak. Apabila anda menukar P sebelum kereta berhenti, ia boleh menyebabkan tuas parkir bertindak seakan brek sekaligus memusnahkan semua proses.
Constantly variable transmission (CVT): Pemanduan yang lebih lancar dengan mengubah nisbah equipment secara berterusan tanpa langkah tertentu. Secara tidak langsung, ia meningkatkan efisiensi bahan bakar yang digunakan.
Since the motor vehicle slowed down and engine speed lessened, the gearbox would change back again to reduced. Nevertheless, the transmission was prone to unexpected failure, due to transmission currently being unable to face up to forces from the abrupt equipment alterations.
Some contemporary transmissions Have a very mechanism that should prevent shifting into the reverse position when the vehicle is going ahead, normally employing a activate the brake pedal or electronic transmission controls that keep track of the car speed.
Mentang-mentanglah guna kereta automatik, tekan minyak terus jalan ramai pula yang ambil mudah tentang penggunaan equipment.

Semasa naik bukit, tukar kepada equipment rendah (D2 atau L) untuk memberikan lebih kuasa kepada enjin dan membantu kereta mendaki dengan lebih mudah.
The clutch packs adhere alongside one another when hydraulic pressure is applied, enabling specified gears to have interaction and transfer ability.
