Sebagai contoh, kos untuk sebuah gearbox automatik asli Perodua Myvi bermula dari RM6,000 termasuk kos pemasangan, tetapi anda boleh mendapatkan gearbox Myvi rekon yang diubahsuai dengan kos kurang daripada RM1,000.
An automatic transmission employs a hydraulic torque converter to be a kind of fluid coupling to transfer electricity and torque within the engine on the load. To transfer ability involving the input and output shafts, it combines hydraulic strain and fluid circulation.
When just one wheel loses grip, the Torsen differential transfers a lot more torque on the wheel with far better traction, boosting the auto's steadiness and managing. This causes it to be perfect for athletics vehicles and all-wheel-travel programs that need specific electricity management.
Autos want gearboxes to provide distinctive equipment ratios for effective ability shipping at various speeds.
The large number of sections, together with the complex style in the valve overall body, at first made hydraulic automatic transmissions Significantly dearer and time-consuming to make and repair than manual transmissions; even so mass-generation and developments eventually have reduced this Expense hole.

As the car and motor modify velocity, the difference between the pressures improvements, causing various sets of valves to open up and shut.
