Proper gear shifting

[ravelcop]

Hi guys!

I just like to know the proper shifting of gear with regards to when to shift to a higher gear and when to go back. I'm tired na kasi of hearing other people say that they do it just by listening to the engine. I know that it should be based from both km/h and rpm guages, im just not sure how.

I also heard that gear shifting contributes a lot to fuel economy. Can anyone explain this also? And what could be the negative effect if you're not doing it right?

in my opinion, you can follow your car manual on proper gear shift changes. but for me, it depends on if i drive fast or not. but usually i shift my gears at around 1900-2200rpm. Changing your gears improperly will cause more wear & tear or fuel consumption.

actually, for people who are "in-touch" with the car (for lack of a better word), yup, pwedeng by ear, sanay na sila, but usually, here goes:

for m/t and semi-a/t (invecs, smg, etc...):

yup, it contributes to fuel economy, if you upshift at the lowest possible rpm possible without stalling the engine and without making your acceleration overly slow. now as to which rpm exactly, depende sa car na yun.

for m/t only:

upshifts or downshifts, do it as soon as possible so that you won't lose revs, which will make things difficult kasi ma-aalangan ang engine and you might stall too.

i've heard of rev-matching, where you bring the rev to the past rev level on other cars to line up the gears, pero i hear that usually from impreza wrx owners, so i guess this doesn't apply to most of us.

negative effect of not doing gearshifts correctly (like unnecessary riding on the clutch, frequent gear grinding), usually the componens to give would be the clutch and gears.

dami pa yan, this is just off the top of my head, balik muna ako to taking an evaluation. let's wait for the others to post.

so paano if you'd like to go back to a lower gear? syempre hindi pwedeng rpm maging basis para dyan.

[nicolodeon]

Here's what I do on my M/T ride:

After I shift gears to a higher, I count "1-2-3" while depressing my clutch at every count. After I reach three, that's when I step on the gas. Allows me to have a much smoother transition to a higher gear. At, dehins umaangil yung engine.

[nugundam93]

actually, the reason for going down to a lower gear, assuming that you're on a level road (no incline), is if the current gear is too low in terms of rpm (speep depends on this, not the other way around) and the engine would stall.

usually you go back to a lower gear when you have already slowed down. Hindi naman kakagat sa lower gear kung masyado kang mabilis.

i got your point jim, iniisip ko lang how to downshift to an appropriate gear. yung tipong hindi mag aalanganin ang makina sa sobrang taas at the same time hindi rin hihiyaw sa sobrang baba ng gear. pwede kaya maging basehan ang km/h?

para hindi tumalon ang revs mo kapag nag dodownshift ka, ganito gawin mo...

- shift to neutral
- blip the throttle
- downshift

depende kasi sa engine size rin kung aling km/h ka mag shift... kung easy driving ako ganito:

2nd - 10 kph
3rd - 30 kph
4th - 50 kph
5th - 60 kph

[wrecker]

normal driving and normal load i up shift at 2k, down shift naman between 1k-1.2k. yun ang smooth sa makina ko.

btw, i drive an ek vti, ihe lang ang mods

yup pwede sa km/h. sa car when driving at 100 km/h at 5th gear i usually downshift to 4th when my meter reads 70 then downshift to third when my meter reads 50.

pero sa jeep iba. when driving at 100 at 5th gear i downshift to 4th when my meter is 80 then to third pag 60.

nasa gearing din kasi yan which differs from one vehicle to another.

o bumili nalang ng automatic heheeh

[ravelcop]

pag nagdadownshift ka ba, bitaw kaagad ng clutch or hinay-hinay lang? diba, nagrerev up pag binitawan agad ang clutch during downshift? does it consume as much fuel as depressing the accelerator?

when i need to use engine break dinedepress ko agad ang clutch especially in downhill situations when I need to assist my breaks. pero on highway driving hinay lang kasi magrerev talaga at magastos sa gas pag dinepress mo agad ang clutch.

AFAIK pag may synchro ang tranny mo pwede mong bitawan ang clutch agad. di lang ako sure kung ganun nga hehehehehehe

[aann]

mga question m ksi varies per vehicle eh...the best way tlga na gawin mo is pakiramdaman mo yng ktse mo..mahirap din yng titignan mo pa yng speedometer tpos iisipin mo pa kng ano ba dpt gear mo sa speed na yun..mabangga ka pa

regarding downshifting: pag hirap makina mo pag accelerate mo e d kelangan mo tlga ng lower gear.

pag upshifting(?): pgka upshift mo tpos hirap makina ibg sbhn kulang pa speed mo nun (unless na kelangan ng tune up at laging hirap makina)

[redpitz]

tama si aann, iba-iba kasi gear shift pattern ng ibat-ibang sasakyan, the best way talaga eh, gamayin mo ung sasakyan mo at pagaralan mo ang pinaka favor na shifting pattern ng auto mo. every day mo idrive ung car mo, for sure makukuha mo rin yan ng tama and pabor sayo, and little by little mainintindihan mo rin kng bakit sa tunog ng makina malalaman pag shift ka na sa down gear or up gear...

May nagsabi na masama daw mag upshift pag below 3000RPM?

[quiksie]

thats not true 1997. Mas maganda nga mas maaga magupshift para mas tipid sa gas.
Tama kayo tantsahan method ang gawin niyo. Pakiramdaman nalang ang tunog ng makina. That's what i do

[jabbronx]

iba iba techniques, depende talaga sa car mo...ako, i rev up (2000rpm) the engine muna before downshifting para smooth pa rin...

downshifting from 3rd to 2nd gear *30-40kph, i usually do this if i need power when overtaking:

1. Rev up (blip) the engine to match transmission and engine speed. Without matching revs on downshift, the engine speed will cause a jolt (kadyot.. ) through the driveline.

2. After matching revs, clutch in, and then downshift.
3. Release the clutch and then accelerate...

sabi ng iba shift early para tipid sa gas.
iba naman sabi shift at high rpm para mareach optimal engine performance.

i'd rather choose engine longetivity rather than fuel savings.
