Can an AT Transmission Coast in Neutral Gear?
1 Answers
An AT transmission should not coast in neutral gear. The functions of a transmission are: 1. To change the transmission ratio, as different driving conditions require different traction forces; 2. To enable the vehicle to move in reverse; 3. To interrupt power transmission, allowing the engine to start and idle, the vehicle to shift gears or park, and cutting off power to the drive wheels; 4. To achieve neutral gear, stopping power output when the clutch is engaged. An automatic transmission is a device that can automatically shift gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. Currently, there are four common types of automatic transmissions for vehicles: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch transmission.
