How does an automatic transmission (AT) work in a Hyundai Solaris?
The Hyundai Solaris automatic transmission uses a torque converter to transfer power from the engine to the transmission. It also has a range of gears that help optimize performance and fuel economy.
Torque converter
*The torque converter is a clutch-like device that sits between the engine and transmission.
* It is filled with transmission fluid (ATF).
* When the engine is running, the supercharger blades in the torque converter rotate, transmitting torque to the turbine blades, which are connected to the transmission.
Transfers
* The Hyundai Solaris automatic transmission has several forward gears and one reverse gear.
* Gears are activated by planetary gears and multi-plate friction clutches.
*Each gear has a different gear ratio, which changes the speed and torque transmitted to the wheels.
Gearbox control
* The automatic transmission is controlled by the transmission control module (TCM).
* The TCM monitors the performance of the torque converter, gears and other transmission components.
* It uses data from vehicle sensors such as engine speed, throttle position and vehicle speed to determine which gear to engage.
Automatic transmission operating modes
* Hyundai Solaris is equipped with several automatic transmission modes:
* D (Drive): Normal driving mode that automatically changes gears.
* S (Sport): A mode that holds gears at higher revs for improved performance.
* L (Low): A mode that limits gear shifting at lower rpm for improved traction when off-road or towing.
* M (Manual): A mode that allows the driver to manually change gears.
Automatic transmission service
* To ensure optimal operation of the Hyundai Solaris automatic transmission, it is necessary to regularly service:
* Check the ATF level and condition regularly.
* Change ATF and ATF filter in a timely manner.
* Regularly check and replace other transmission components such as the torque converter and gears as necessary.
