| [#5] N 波問題 如果係用液壓轉換器波箱就唔洗N啦， DSG就踩實迫力會自動解開離合器一樣唔洗N， 自動波轉來轉去做嘜：） |

| [#9] N 波問題 自動皮都係行液壓. 轉波多solenoid valve易壞 Ｄ波長迫力就冬菇易壞 睇你想整邉樣. 換solenoid valve好多車唔使落波箱， 換冬菇就要. |

| [#20] N 波問題 A long answer I found on the internet... ----- When the car is in D and you start the engine the hydraulic pump in the automatic transmission is not providing fluid pressure until the engine starts. This fluid pressure is used to engage clutches in the transmission to engage first gear or reverse. An automatic transmission does not have gears like a manual transmission which are physically meshed into one another or engaged. The gears in an automatic transmission are always engaged or locked in but they are coupled to the drive shaft by multiple different clutches that are selected either by you or automatically. This is called the planetary gear and clutch system and it is very difficult to conceptualize. In an automatic transmissions N is actually the same as D in that none of the clutches are engaged except in D there is a mechanical connection to an internal transmission brake. This brake has nothing to do with your wheel brakes and it come on mechanically so the engine does not need to be running for it to work. In D when you’re at a stop the main forward clutches are engaged and the torque converter is providing pressure to rotate the forward gear but it does not rub or wear when it is doing this. Because of this resistance to free rotation in the transmission the engine begins to slow. In a modern car there is an idle control valve which the computer opens to increase air entering the engine so the engine does not stall. So there is actually more air entering and the computer senses this and adds a bit more fuel as well. So in D at the light your car will use a little more fuel than if it was in N. Also the wheel brakes are not rubbing but are stopped and they will not wear at all while holding the forward creep of the car when in D. The forward creep is caused by the transmissions torque converter. There is nothing slipping or wearing or heating up to any significant extent in there. It’s all done hydraulically and nothing is wearing to worry about. BUT!!!! When you are in N and the engine is turning and the wheels are stopped then for this to occur the main forward clutch is disengaged and it is SLIGHTLY SLIPPING. So the clutch plates are wearing. So you are actually wearing out the main wear component in an automatic transmission being the clutch plates if you shift from D to N at a stop. The only advantage is your saving a very small amount on fuel. Personally I DO NOT and I have been told by an automatic transmission engineer that you should never shift the transmission from D to N at the lights. The reason being you are wearing your clutch plates in your transmissions. It also gets hotter because of the friction and the dirtier transmission oil then contributes to other component failures. Also it’s dangerous to be sitting there in N. You may need to drive away all of a sudden to avoid an accident but in N there is less chance of do this. You also may select the wrong setting like R when you wanted D. If N should be selected at the lights then engineers would have incorporated this into the design. But they did not. On some fuel saving cars the engine now shuts off at the lights so obviously N is selected automatically by the computer during the shutdown period so the car can be restarted. But the engine is not turning so the clutch plates are not slipping and wearing in this type of fuel efficient car. Also if your car vibrates in D at the lights then you need to get it serviced. It should not vibrate excessively at the lights if everything is working fine. |
