Automatic transmission with 4 steps
* Advantages:
*Simpler and more reliable design
* Less fuel consumption at low speeds
* Flaws:
* More limited range of gear ratios
* Less smooth gear shifting
*Higher engine speeds on the freeway
Automatic transmission with 6 speeds
* Advantages:
* Wider range of gear ratios
*Smoother gear shifting
* Lower engine speeds on the freeway
* Increased fuel efficiency
* Flaws:
* More complex design
*Higher manufacturing and maintenance costs
Conclusion:
The choice between a 4-speed automatic transmission and a 6-speed automatic transmission depends on your individual needs and priorities.
*If you are looking for a reliable and fuel-efficient transmission, a 4-speed automatic transmission may be your best choice.
*If you want smoother operation, better fuel economy and lower engine speeds, a 6-speed automatic transmission is a better option.
