3: Restricts the transmission to the lowest 3 gear ratios. Within a 4-speed automatic transmission, this is often made use of to circumvent the vehicle shifting to the overdrive ratio.

To vary gears, the hydraulic automatic works by using a combination of interior clutches, friction bands or brake packs. These units are used to lock selected gears, Hence setting which equipment ratio is in use at a supplied time.[15]

Tekan pedal brek dengan lembut dan secara beransur-ansur untuk mengawal kelajuan kereta. Jangan menekan brek secara mendadak kerana ini boleh menyebabkan kehilangan kawalan.

Kalau di taska, takut ada taska yang terlepas pandang dan tak cukup tangan nak jaga (sesetengah taska memperuntukkan seorang untuk menjaga 3 orang bayi- mungkin)

Under the pores and skin, nevertheless, this gearbox is effective very like a guide, but using an electronic Command unit selecting when to alter equipment, as opposed to the motive force calling the pictures.

"Financial state" (also referred to as "Eco" or "Comfort") modes trigger equipment shifts to happen at lessen engine speeds to lower fuel intake.

The equipment selector is definitely the input by which the driver selects the functioning method of an automatic transmission.[33] Ordinarily the gear selector is located involving the two front seats or link bantuan about the steering column, nevertheless Digital rotary dials and press-buttons have also been sometimes made use of For the reason that 1980s, together with drive buttons having been Utilized in the nineteen fifties and 1960s by Rambler (automobile), Edsel, and many famously, by Chrysler.

Reduce gears have more substantial cogs and empower the engine to deliver higher amounts of force with no car or truck moving quickly, which is ideal when you are driving slowly and gradually or uphill, according to the journal Transportation Analysis Component A: Typical. 

Low (L): This posture gives for motor braking on steep hills. What's more, it presents for any lower gear ratio for getting started when seriously loaded.

Jika kekotoran yang ditapis melebihi kapasiti ini, masalah aliran ATF tersumbat akan berlaku dan menyumbang kepada masalah gangguan tekanan hidraulik di dalam gearbox. Pastikan auto filter diganti mengikut jadual ataupun setiap kali anda servis minyak ATF.

Jangan dan jangan dan jangan sekali lagi. Tiga kali saya menyebut jangan kerana sebagaimana yang anda telah ketahui, semua kereta baru zaman sekarang menggunakan hampir sepenuhnya sistem elektronik.

Apabila memandu pada kelajuan rendah atau menaiki bukit, gear rendah digunakan. Equipment rendah mempunyai gigi yang lebih besar yang membolehkan enjin memberikan lebih banyak torque kepada roda.

Jangan menukar gear dari D ke R atau P semasa kereta masih bergerak kerana ini boleh merosakkan gearbox.

Electric power and torque curves for two case in point automobile engines Considering that the torque and electricity output of the inner combustion engine varies with its rpm, automobiles driven by ICEs have to have numerous equipment ratios to keep the motor inside of its power band to create optimum electric power, fuel performance, and easy Procedure.
