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

[Starex_Gold]

bakit lahat yata ng AT na nasubukan ko (except for the brio amaze) may delay talaga when you floor it.

Sa Brio pa talaga ano?

Try mo sa Nissan GTR na bago wala din delay

More than the transmission, it's the drive-by-wire throttles that give that feeling of delay. A 90s car, regardless if MT or AT, will have better throttle response than most cars today.

DBW throttles have that delay to improve fuel economy since most people just suddenly jab at the throttle which isn't a very thrifty technique.

ayaw mo may delay? press the brake with your left foot, accelerator with your right. or heel-toe mo. then release the brakes. magastos lang sa goma. takaw sunog atf din pag lagi mo ginagawa.

di naman from STOP bro, pag umaandar na, minsan kasi mas gusto mo ifloor depende sa situation.

yup ok yung arangkada ng brio nun tinest ko.
ang inayawan ko lang yun "kabig" ng steering wheel nya maski mababaw ang lubak.

it's the nature of the beast, po.
ATs have a liquid coupling that has an initial slippage... we can only minimize it by clever engineering, but can not entirely get rid of it.
and, i believe, it gets less noticeable with smaller (lower momentum) vehicles..

thanks for sharing.


thanks din sa mga nagreply, mukhang magiintay nalang ako magkaroon ng mt units
kaya ko lang naconsider yung at dahil wala available mt units sa car na gusto ko

pwede sya pa adjust bro? would casa tech know how to do this?

Noob question lang. Bakit mas matipid ang MT kesa sa AT?

Halimbawa normal driving lang, both Diesel engine. Pansin ko sa AT namin halos hindi umaabot ng 2.5k RPM while sa MT, madalas umaabot pa siya sa 3k RPM. Are there any technical explanations kung bakit mas matipid pa rin ang MT? Thanks guys.

There are more energy lost in liquid than mechanical coupling.

A/T for convenience? There is nothing convenient about waiting an eternity for your transmission to respond to your throttle input.

Biggest factor is WEIGHT; an A/T car weighs more than its M/T equivalent. More weight = more effort from the engine to propel the car, therefore more fuel consumed.

Nope. Usual difference of MT vs AT is less than 50 kilos. Kumbaga para ka lang may sakay na bata with an AT car. That isn't enough to explain the usual 1-2 km/L difference of an MT and AT car.

It has more to do with the fact that there is just more power loss from engine to wheels with an AT than an MT.

Must be a crappy AT then. Most new AT's shift faster than the average person.

Ang dami kayang driver more than 1 second magshift ng MT.
