Honda Jazz/City CVT Problems. Anyone?

[suysuy]

*xircom

baliktad sa akin, ok ang acceleration pero once na lift mo na foot mo sa gas pedal, ang bilis bumaba ng speed lets say nasa 60kph ka, bababa talaga siya up to 20kph then parang naka neutral na ang sasakayn kasi hindi na siya hihina pa. nakapako sa 20kph. I also hear a whistling sound

Just got my car kanina. All I can say is that there was an improvement. BUT

BUT: The RPM drop is still there. Yun lang ang naiiwan na problema. However, that jerky feeling is not there anymore. Im glad. When you lift your foot of the gas, it does not decelerate very quickly anymore. It felt normal again.

What they did is they replaced the CVt Fuild and recalibrated it. Also they found two spark plugs that are slightly loose.

im getting better mileage too. this is good

try shifting it manually so you can hold the tranny in a higher gear to see if it keeps happening.

Very informative thread. My city is nearing 20k km and i'll be watching out for changes in the CVT behavior.

Has anyone here tried changing the CVT-F themselves? Can you use normal ATF?

[speedyfix]

definitely do not use atf for cvt trannies. viscosity is totally different and you'll end up destroying the tranny.

im back guys. why? because the problem is back. and even worse!!!!

muntik ako ma alanganin sa pag overtake nung isang araw. kasi ganito ang nangyari

pag tapak ko ng gas half way down, syempre nag accelerate na, puchaks, biglang parang nag dip ang rpm to just 1000rpm then bumalik agad to 4k-5k. nawalan ako ng acceleration for how many milliseconds due to that superjerk!

ive scoured for many infos sa net and Ive found a new one.

Recently due to a recent scare driving jerkiness on my CVT Jazz, I was forced to reset the ECU/PCM and disconnect the battery to determine if this was the reason for the problem. In the end, it turned out to be a bad EGR.

what is that EGR valve? meron ba lahat ng cars nito lalo na ang Honda City? Pupunta ako ulit bukas sa dealer

Sorry bro., can't help you here. I have not experienced this phenomenon on our almost 4-yr old Jazz CVT...

Please keep us updated on any developments....

hindi na muna ako pumunta. eh kasi tumaas nanaman ang gas. at itetest drive nanaman ito. mauubos lang gas ko.

well, im starting to hate this car. baka palitan ko nalang ng new lancer. CVT parin naman y un at mas maganda pa hehe.

it really starts to irritate me, napakajerky imaneho at 40-60 light throttle. everytime I take my foot of the gas the rpm will drop like crazy to almost zero and come back up to 1200rpm. and you can feel the car as if someone is applying brakes for milliseconds.

its just plain irritating. lalo na sa traffic. you can't coast smoothly!

[suysuy]

up ko lang. sino pa ba dito merong issues?

[mbeige]

Bad EGR? Bakit hindi mo patanong sa casa ito. EGR is exhaust gas recirculation device - it is primarily for emissions so that your exhaust gases are brought back into the intake to burn them, rather than out the exhaust as emissions. Maybe not a faulty EGR but the lines leading to it? Just a suggestion. I don't know if EGRs in modern cars have the old style vacuum control or electric na.

[baludoy]

have you tried having it diagnosed in another casa? or maybe even in a reputable shop w/ no direct honda affiliation bro (even though i presume it's still under warranty)? who knows maybe an outsider w/ another approach to your car's problem may just hit the g-spot

i'm just saying this because in our jazz's case, we just recently had it serviced outside the casa for the 1st time after having its warranty elapse early this year & so far the car is performing well

[speedyfix]

bring it back to the person that fixed it. sayang binayad mo kung may problem ulit.

[afrasay]

Have someone in the casa test drive the car with you in it.

suysuy, I have a city and I think we have the same problem - the RPM fluctates when the speed is around 30-40kph and when the gas pedal is released, it's like an engine brake.

Right now, it's been at the casa (fairview) since thursday, they said they have given it a battery of tests and their final diagnosis is a bad shift solenoid. I don't know exactly what that is but it costs 17k (my car is out of warranty already - 110k and 4 yo already).

I'm going to the casa a little later to understand it better. I just want to make it clear with them that I don't want to spend 17k and it turns out that it's not the problem.

Does anyone here have an opinion about the diagnosis - bad shift solenoid?

[aoxy]

Just to update everyone. I got my City back from the casa last Thursday with the replaced shift solenoid and the problem is solved. The RPM is now steady when it's steady on the gas pedal. And no more engine brake-like feeling when I release the gas pedal. I just hope it stays fixed.

Hope this info helps.

[suysuy]

wow! thanks for that info!!! at last nadagdagan idea ko kung ano dapat ipapacheck ko. ive been scouring the net for infos

so far nalaman ko is

1. EGR valve might be dirty
2. Throttle body needs cleaning
3. Shift Solenoid.

but what teh heck. 17k? well, nasa warranty pa naman ito. feb 2006 ito nabili ko meron pa akong isang taon. thanks for that info

so far ok na ba ngayon city mo? wala na talagang engine brake feel?
