AT vs MT

That is especially when you should run an auto.

As I already said, the torque converter is a fluid coupling. So there is a power loss through slippage. On a full race car, they use a different set up altogether.

Drive what you want.

In addition to the very important job of allowing your car come to a complete stop without stalling the engine, the torque converter actually gives your car more torque when you accelerate out of a stop. Modern torque converters can multiply the torque of the engine by two to three times. This effect only happens when the engine is turning much faster than the transmission.
At higher speeds, the transmission catches up to the engine, eventually moving at almost the same speed. Ideally, though, the transmission would move at exactly the same speed as the engine, because this difference in speed wastes power. This is part of the reason why cars with automatic transmissions get worse gas mileage than cars with manual transmissions.

To counter this effect, some cars have a torque converter with a lockup clutch. When the two halves of the torque converter get up to speed, this clutch locks them together, eliminating the slippage and improving efficiency.

Items in bold directly relate to that A340 in the MA70

so you mean to say...that the auto is pretty equal to manual?

 

[Allan_MA70]

the auto is heavier and has more mass to spin then a manual BUT much more drivable, faster at the drags and has a taller overdrive for better fuel economy but for circuit racing yes a manual is better but thats the only place!

yup. but its not like your going to bust a tokyo drift and turn the streets into tracks, right? its more likely that your going to go in a straight line rather than making a "circuit/track" in the city. with that said, what makes me want a manual, is that chicks dig guys that drive manual :wink:
