What is the difference between a mechanical automatic transmission and an automatic transmission?
1 Answers
Here is an introduction to the differences between a mechanical automatic transmission and an automatic transmission: 1. Using gears to reduce speed: Compared to a regular automatic transmission, a car with a manual-automatic transmission can switch to manual mode during long downhill descents. The advantage of this is that it allows direct control of the vehicle's speed through the transmission, eliminating the need to continuously apply the brakes. Prolonged braking can cause the brake discs to overheat, leading to brake fade and potential failure. Additionally, coasting in neutral is not advisable. Therefore, experienced drivers with manual-automatic transmissions often opt to shift to a lower gear and combine it with intermittent light braking. 2. Using gears for overtaking: Some manual-automatic transmissions may not be as responsive and might not immediately understand the driver's intentions. If there is a delay during overtaking, it can be somewhat risky due to inaccurate estimations. In such cases, switching to manual mode allows the driver to downshift first to increase engine speed, then upshift to overtake smoothly.
