Four-speed automatic transmission (automatic transmission) Hyundai Solaris
Design:
* Hydraulic torque converter
* Planetary set of three planetary gears, two brake bands and two clutch packs
Gear ratios:
| Transfer | Gear ratio |
|—|—|
| 1 | 2,846 |
| 2 | 1.545 |
| 3 | 1,000 |
| 4 | 0.696 |
| Reverse | 2,267 |
Peculiarities:
* Electronic Control Unit (ECU) Control: The ECU uses sensors and solenoids to select gears, adjust fluid pressure, and control torque converter lock-up.
* Torque Converter Lockup: Locks in 3rd and 4th gears, reducing slip losses and increasing efficiency.
* Adaptive Gear Shift Algorithm: The ECU adapts to driving style and road conditions to ensure optimal gear shifting.
Advantages:
* Smooth gear shifting
* Ease of driving in urban environments
*Easy to maintain
* Lower cost compared to more modern automatic transmissions
Flaws:
* Relatively low number of gears
* Higher fuel consumption compared to more modern automatic transmissions
* Less acceleration dynamics compared to more modern automatic transmissions
