Demystifying Car Transmissions: A Guide for Malaysian Drivers
JamesFeb 23, 2024, 09:25 PM
A transmission is a device that changes the speed and torque from the engine, generally can be divided into manual transmission and automatic transmission.
Explanation of transmission types
The transmission is a device that changes the speed and torque from the engine, most transmissions are composed of many gears of different diameters. Transmissions are primarily used to modify the torque and speed of the engine crankshaft to meet the varying requirements of driving wheel traction and vehicle speed under different driving conditions such as starting, accelerating, driving, and overcoming various road obstacles.
Classification of transmissions
● Manual transmission
● Automatic transmission
● Manumatic (automatic with manual mode)
● Fixed gear ratio transmission
● Continuously Variable Transmission (CVT) / CVT with simulated shifts
● Dual clutch transmission (divided into dry and wet)
● AMT transmission
● ISR transmission
● Hybrid drive special transmission (DHT transmission)
● Three-clutch electric drive transmission
● Electronic CVT (E-CVT)
The parameter "7-speed manumatic" in the parameter configuration page refers to: this model is an automatic transmission with manual control gears, and there are 7 gears.
If you see "7-speed CVT manumatic", this refers to the transmission structure is a CVT structure, but with 7 simulated gears.
The function of the transmission
The transmission plays a variety of roles in the operation of the vehicle, for example:
● It allows the car to run at a very low and stable speed, which is difficult to achieve by just relying on the lowest stable speed of the internal engine alone.
● The reverse gear of the transmission allows the car to drive backwards.
● Its neutral gear allows the car to disconnect the engine from the drivetrain for long periods of time when starting the engine, parking and gliding.

The upgrade of the Myvi is not to be unconventional but to strengthen the brand and market, ensuring that the Myvi continues to maintain its irreplaceable position in the new round of product competition.
Perodua Traz VS Toyota Yaris Cross, where does the Traz fall short?
Before the official launch of the Perodua Traz, market expectations were actually very high because it shares the same DNGA platform as the Toyota Yaris Cross. However, sharing the same platform does not equate to the same experience, and the Traz's final performance has indeed been disappointing. Perhaps it is precisely because of the delayed launch that it has almost no competitiveness in the current competitive environment.
