2014 Honda City (Gen 4)

I have a brv pero same din lang naman ata sila. Owner's manual says it's ok, pero best to consult your manual, nakalagay dun lahat. Ganto ginagawa ko kapag mahabang pataas o pababa. Huwag mo nga lang gawin habang nakaapak ka sa gas.

I think hindi ata ako umaapak sa gas kapag D to S pero kapag S to D hindi ko nirerelease ung gas pedal

is it safe to shift from D to S to engine brake on corners? I usually downshift on corners when using mt to assist my brakes.

just use your brakes. cvt repair is not possible. brake pads are cheap

does it really hurts the transmission when you engine brake?

Quick question...how significant is engine braking in terms of its overall contribution in slowing down a car or bringing it to a full stop vis a vis the brakes? I'm thinking that if the contribution is insignificant..say for example 10% engine brake-90% wheel brakes, is it even worth it to risk additional wear or possibly breaking your transmission(if it even has an effect at all) vs just using the brakes to stop the car?

**By engine brake i mean intentionally selecting a lower gear to slow down the car (not lifting your foot off the gas pedal and slowing down in gear).

It’s significant when you are going downhill and you constantly use your brakes. Naka experience ka na ba nung “lumusot” ang preno? Id rather loose my transmission than plunge into a ravine.

this is an entirely different scenario, pag lumusot preno even if you do an engine brake you will still (most likely) plunge into a ravine engine brake won't stop your car either, i agree with n_spinner brake pads/shoes are way cheaper than tranny repairs, imho

as i've read on some articles and also my own experience when you engine brake (shifting to lower gear to decelerate), you have more control on the speed specially when you do not trust your brakes. ramdam ko talaga kapag mahaba ung downhill parang lumalalim ung feel sa brake pedal parang ramdam ko nawawala ung kapit nya. kaya kelangan talaga ung engine braking.
some says engine braking affects the transmission but other says it doesnt.

the best way is to simply drive slower.
it doesn't cost anything.

imo he is trying to say that assist the brake thru engine braking to avoid or before resulting to loose brake

Engine braking in itself will not damage your transmission. It's perfectly fine for a car to stay at a high rpm (which is when engine braking works).

The problem is when coming from low rpm then suddenly going to high rpm without proper rev matching. When driving a manual, most people don't rev match - they just slot it to a lower gear and release the clutch and wait for the revs to rise. That puts a lot of stress on the clutch and transmission - you can avoid it by revving the engine to the expected rpm of the lower gear before releasing the clutch.

For automatics, most non-sports cars don't have auto-blipping, but the ECU is smart enough to be conservative about the downshifting (or ratio adjustment for CVT) to not burn out the clutch/pulleys.

Bottomline - engine braking is crucial for continuous downhill driving, and it isn't harmful to your transmission when done right.

Well my scenario is our family car full of passengers plus baggage & cargo, going down thru marcos hiway coming from baguio. Its a gen1 kia carnival. Mabigat na nga yung kotse to begin with. After that experience i always use engine brake na going downhill.

Hehe ano na ba talaga, pag downhill alalay talaga ako sa brake then bawas gear using paddle shift.

Before IIRC I posted it also here, nakasanayan ko pambawas speed kahit hindi downhill yung paddle shifters, then I realised mas mura nga ang brake pads kesa palit transmission assembly hehe

Tulong lang naman sa main brakes yung engine brake sa downhill. So the most that you will use engine braking is 30 minutes? I’ve been doing this on all our previous vehicles even the current one. No damage naman sa tranny.

ganito rin ung iniisip ko e. as long as sa pagdownshift hindi sya bglang maghigh rpm. kaya sa mt I downshift on each gear like 5th to 4th den 4th to 3rd. hindi ung 5th tapos downshift to 3rd agad or 2nd cguradong iiyak ung makina.
as for the cvt dito ako questionable sa engine braking. ang alam ko dahil automatic nga when you shift from D to S to engine brake the car is smart enough to shift to the most appropriate gear/speed kaya sa tingin ko hindi sya harmful practice. I just need others opinion regarding this and looks like we share the same point of view.

Hindi naman masama yun bro kahit nagpapaddle shift ka to lose speed. But generally I coast rather than engine braking pag kaya, normal brakes pag kailangan. Pag downhill like Baguio saka lang ako malakas mag engine brake to lessen the stress on the brakes.

been to baguio last month with full passengers and full baggage on the trunk. mabigat talaga ung load. I didnt use engine braking just relied on the brakes ok nman. moderate lang speed ko kasi ang talagang prinoproblema ko ung suspension ng car baka masyadong mabugbog lalot uneven ung pavement natin at may mga bumubulagang potholes pa sa naguilian road hindi kasi ako masyadong familiar sa daan.

you wont stress the brakes if youre slowly going downhill.

thats the thing, guys here probably have kids. safety is of concern.

i see so many guys going down baguio without brake lights... engine braking even accelerating!

I go up and down baguio quite frequently. Speeders are most often the UV express vans.
