What is the difference between a 6-speed automatic and a 6-speed manual-automatic transmission?
2 Answers
6-speed automatic and 6-speed manual-automatic transmissions have different internal codes, with the 6-speed manual-automatic allowing manual gear shifting. However, both are supplied by Aisin. Models featuring the 6-speed automatic include the new Bora, Santana, Santana Gran Santana, and Jetta, while representative models with the 6-speed manual-automatic transmission include the Lavida, Gran Lavida, Sagitar, and Tiguan. Below is an introduction to the manual-automatic transmission: 1. Overview: A manual-automatic transmission is a gearbox that combines manual and automatic shifting functions. This technology was developed to enhance the fuel efficiency and control of automatic transmissions, allowing drivers to manually override the computer-determined shift timing, thereby improving driving control and enriching the driving experience. 2. Working Principle: Structurally, a manual-automatic transmission mainly consists of a standard gearbox (similar to a manual transmission), an electronically controlled clutch, an automatic shift mechanism, and electronic control components. The electronically controlled clutch automatically engages, disengages, or "slips" the clutch as needed, with the transmission ECU controlling a stepper motor to move the clutch fork for engagement or disengagement. The automatic shift mechanism automatically selects the appropriate gear as required, typically using two stepper motors controlled by the transmission ECU. The gear lever setup is similar to that of a conventional automatic transmission, with no clutch pedal.
I understand the difference between a 6-speed automatic transmission and a 6-speed automatic transmission with manual mode. The automatic transmission relies entirely on computer control for the shifting process. You just need to press the accelerator and brake, and the system automatically switches between the 6 gears, making it very suitable for city traffic jams or novice drivers, as it is simple and worry-free to operate. The automatic transmission with manual mode, on the other hand, adds manual control functions on top of the automatic mode, such as paddle shifters on the steering wheel or the gear lever, allowing you to manually upshift or downshift. This gives you more driving freedom, for example, manually downshifting to increase torque when climbing mountain roads. Technically, the automatic transmission with manual mode just adds an electronic circuit that allows the driver to intervene in the decision-making process, without changing the basic structure, but it provides a more flexible driving experience.
