Battle of the Transmissions: M/T vs. A/T

[Retz]

A/T for daily/traffic drive and M/T for weekend sunday drive.

Half clutch will result more clutch wear

At first, once you get the hang of it you can use less throttle each time. I used to use 3000 rpm in a 1.3L Honda City, much easier than balancing it on the throttle and clutch.

a/t for leisure and heavy traffic driving, m/t for kick ass driving

but i'm comfortable with both. the only obvious difference is that a/t maintenance is much costly

making a call thru your celfone and eating your fave snacks are acceptable BUT texting while driving is a big NO NO !

[Michael Garcia]

to sum it all
flexibility and control MT
convenience AT

other factor car sharing mas flexible ang automatic
mas madali ipahiram ang AT

MT cars are cheaper
better fuel economy which is dependent on driving style
theoritically maintenance lamang ang MT

hirap lang talaga masyadong pampered tayo dahil technology is offering convenience kaya nagtatabaan tayo
MT offers konting additional calories burn

pero minsan convenience has its perks
kunwari nasprain ang left ankle mo sa basketball. pwede ka pa rin magdrive ng AT

Bakit sinasabi ng iba mas malakas daw umarangkada ang mt sa at? Sa tingin ko naman pareho lang sila dalawa. Pag magoovertake ka gamit ang AT magbaba ka lang ng 2 gear tapos apak na sa gas. Same lang naman sa manual diba?

Usually less yung powerloss sa MT vs conventional AT because MT transmissions are directly connected to the drive wheels while conventional AT transmissions use a torque converter. The torque converter itself can be thought of as joint between the engine and an AT transmission. Imagine the connection between engine and transmission as 2 shafts, in between these shafts is a thick fluid. When the shaft from the engine spins, the fluid also starts to spin, this then makes the shaft going to the transmission also spin.

While this allows an AT to make smooth starts without need for a clutch, spinning the fluid in the torque converter wastes engine power when compared to the direct connection of a MT. This wasted power is power that could have gone into making the car accelerate faster, hence the advantage.

That's why some cars like Fords with "Power Shift" transmissions instead use a dual clutch transmission. Which in effect it is a MT transmission that is operated via computer so that it acts like a conventional AT. The downside of these however as it won't be as smooth as a conventional AT.

One final note is that all transmissions are not made equal. Each transmission can be made to give more acceleration or more top-speed, this greatly affects acceleration and fuel consumption. top-speed setup transmission usually give better fuel consumption than acceleration setup transmissions, because of this some AT transmissions are given topspeed oriented gearing compared to their MT versions to match their fuel consumption, in exchange for slower acceleration.

Hope that helps but correct me if im wrong.

ang notion kasi naka 'D' ung A/T. pero pwede naman ilagay sa lower gear.

Diba ang powershift ng ford ay dual clutch transmission? Katulad ng transmission ng bagong focus. DCT na sya kaya parang manual na din sya kahit automatic?

Yes it is, so parang manual din yung hatak nun. Yung only downside ata is that mas mabigat yung dual-clutch na AT. Yung smoothness niya sa pag shift at paggalaw, depende po sa softare ng manufacturer.

Ok thanks
