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

[p_borj]

*woohoo - yup, safety first pa rin, dapat maingat sa driving. may kainitan pa siguro tayo sa pagmamaneho, pero ang pagiingat pa rin ang number 1 priority. Amen!

By the way, ipagtatanggol ko naman ang A/T this time. Kapag passenger naman kasi ako, mas gusto kong sumakay sa A/T cars dahil..

Para hindi ako urong sulong kapag nag-accelerate hehe, mas smooth driving kasi diba pag A/T unlike M/T na kapag nasa low gears eh malakas ang engine braking haha.

Depende rin. We had an A/T EK Civic VTi back then, ang tindi ng shift shock. It's like those jeepney drivers who don't know how to modulate their clutches, yung biglang bumibitaw sa clutch kahit first gear. Ganun yung Civic lalo na pag biglaan.

But again, some automatics are silky smooth. Ngayon hindi ko na namamalayan na nagshishift ng gears. Kasi walang kwenta din naman yung gear indicator sa gauge ko kahit 3 yung nakasulat pwedeng nasa 1st or 2nd gear.

pag sa AT, changing of gear is based on RPM or KPH?

[speed unlimited]

The most battle tank manual transmision willys jeep like the M38 and the valve in head engine.

RPM, speed, engine load, and throttle position.

I am a manual-gearbox stalwart and I do note that downshifting on them can be clunky...unless you have the proper technique.

I subscribe to throttle-blipping on downshifts. Basically it involves pressing the gas pedal a little before re-engaging the clutch in the lower gear. This is to match the road speed and the engine speed. When done properly, when the lower gear is engaged there is hardly any shock through the driveline. Takes a bit of practice but it's easy to get used to - and very useful when overtaking.

Combine this technique with braking and you have heel-and-toe, but that's another story...

There are some very very good automatic "slushboxes" as you said. EG and EK Civic A/Ts are notorious for shift shock, but my mom's FD exhibits almost none of it. It just slurs through the gears, yet keeps very little of the "rubber band" effect of kickdown when you need overtaking torque.

Honda seem to have grafted the same A/T to the GE Jazz although with much more economy-biased programming...it's just as smooth, but it also saps/masks the Jazz's engine capabilities.

Toyota A/Ts, as on my sister's ZZE121 Altis, are smooth also. However the rubber band kickdown effect is much more noticeable, with greater lag between kickdown and actual downshifting.

Sa Honda CVT wala pa akong na experience na shift shock. Parating smooth shifting lagi. Kaso mahirap maintain CVT as it requires a different kind of fluid.

With other automatic cars I've driven (Mitsubishi Lancer and Mazda Familia and MPV) shifting was not as smooth as CVT.

The problem is CVT opens a different can of worms.

The problem is CVT opens a different can of worms.

My thoughts exactly...
- engine modifications are limited due to the CVT's power handling (except, maybe, if you own a Nissan Murano...)
- on the Jazz and City, the CVT tends to eat its own transmission supports
- like you mentioned, they can be very finicky with transmission fluid
- CVTs are just a different animal from a more ubiquitous torque-converter A/T
- who really knows how to repair a CVT in the country anyway?

CVTs are a good idea but the execution still seems wanting. Hasn't stopped Audi from offering most of its smaller cars with it though, it seems...

pag sa AT, changing of gear is based on RPM or KPH?

The reason I asked kasi, my 4m40 FM changes 1st to 2nd gear at 1.5RPM and around 20kph, pero from 2nd to 3rd gear, KPH should be around 40kph even if I pressed the RPM up to 2.3 .. . ANyone know why this happens?

My friend's FM usually changes 2nd to 3rd at 1.5-1.7RPM wiht 30-40kph... I'm diligent naman in maintaining my ATF.

any help would be appreciated

M/T for skilled drivers, A/T for lame ones, A/T speaks for itself=automatic-the transmission will change the gear for you.

[istan]

Its based on what your feet does. Lay off the throttle to shift down, Press it to shift up. What your feet does is probably different from what your friend's feet does.

[woohoo]

Troll alert warning ON, too...

A/T is for lame drivers??? :nono:

yes! A/T is for wusses, girls and old people! real men use manuals!

lol.

^---same goes for the WRC/DAKKAR/WTCC/jWRC drivers.....

as well as all the owners of the ferraris, porsches, LF-As, and the multitude of other supercars that have auto trannies that can shift faster than your eye can blink!

lahat yon pang non-real men!

hahahahahaha

Pepsi vs. Coke, white sauce vs. red sauce, Dell vs HP... :D Nobody wins in these types of arguments. Fun to watch, nevertheless.

Even though A/T does shift for you, modern ECM/PCM allows the driver to influence the shifting progression or characteristics. Whether it be in the way the gas pedal is depressed, or a mode button to tell the computer to either shift for economy or performance.

If I was into motorsports, manual tranny or DSG, hands down. For everything else, it's A/T. I'd like the advantage of having a free hand available for more important tasks with the lady passengers. :D

my friend, to fully appreciate A/T, one has to be frequently stuck in traffic...or be stuck driving a car/truck on full load up an incline.

and btw, even lame drivers have the right to drive; it's the reckless, abusive ones that are the real problem. i'm quite sure that is the general consensus B) :peace:

btw, i prefer M/T for as long as my knees can take it(so far so good)

but then you can't make the excuse of your hand "slipping' while trying to shift :D
