Probably the wet clutch slipped coz insufficient torque, ultimately overheat and the TCU release clutch pressure.

In these cases torque converter is better than wet clutch. This is not the first time Preve Exec owners complain the car underpower when going uphill....especially when stop in the middle of the hill and move again, gg.com.

Will performance cvt oil like redline brand solve this 'clutch slipped' issue?

Semua salah Thean Hou Temple.

Campro is underpower without turbo. Buy Preve must be CFE, otherwise better buy Persona or Saga.

30% is already very steep. Though I would think most cars would still be able to climb up the slope albeit slowly, but steady. Maybe the car is faulty, or it's just that the mechanism of the gearbox coupled by the engine output are not very good.

Not able to move up the slope is rather serious. I wonder if the driver has reversed all the way down if it happens that the car is stuck halfway up the slope, unable to climb up anymore. THat would be hilarious.

Proton Dr. M will say they don't have hill assist, pay more to include one.


Well anyway, if 30% already having problem, I still see countless Preve reached Genting top, the entire journey to the top won't have such steep slope?

maybe the catf overheated for some reason...
personally will try to make use of the hand brake, even though driving with auto transmission, the launching will be safe with "manual hill assist".

That's really steep though... the suggestion by Proton is rubbish of course, and it's a problem, but.... such a steep gradient isn't common. I highly doubt all the way to Genting it's anywhere near that steep.

Also, will the Rusa roll? Given that it has really long overhang front and back, and rear wheel drive and high center of gravity.

eh true also... if 31% cant go up. Then how does all those preve go up Genting? But then again, I never paid attention to the slope angles in genting, is it all of them are lesser than 30% inclination? hmm.gif

There's a rumor, Saga IAFM with CVT not released in Indon due to the fact road over there more haram than Msia and they failed to go up on certain hilly or mountainous roads over there.. (mind you the archipelago are full with Volcanoes and there's no shortage of gradient roads up the hill)

Perhaps that's related to this?

However, those previous Saga, Gen2, Persona and Satria Neo + Exora which still retained their Ktard slushbox 4 speed auto still able to climb.. (non turbo)

On the journey up to top, I do remember there's this one sharp turn to the left is freaking steep. I believe it should be more than 30% (based on the diagram).


Btw, anybody has some 'in-the-dash' photo of such 30%-ish hill?

Since Campro Turbo definitely have better torque than 1.8L NA engine (even more than 2.0L NA), I wonder how come no people complain Altis 1.8L CVT can't go up Tien Hou Temple?

I own a Preve so I can answer that.

The car has no problem going up the hill at 30% gradient...until when there's slow traffic ahead on the slope. The CVT gearbox tend to get "confused" when you try to drive slowly on the hill. The engine speed fluctuate from 2-3k rpm. It felt like gears being shifted 2nd gear straight to 4th gear back & fourth.

It's annoying as hell.

Because you've been deceived by the numbers in the spec sheet alone doh.gif

How the torque is delivered and how the power is put down is more important and paints a better picture.
The CVT in Altis vs the CVT in CFE models are miles apart. doh.gif

I suspect the problem lies within the software calibration between the engine & transmission.

I don't get the same problem with Gen2 slushbox.

i can perfectly understand the issues a preve may face as i too drive a fat car, and when going steep parking ramps/hills, the idea to downshift to even gear 1 (almost stalling on gear 2) for a manual raised a lot of eyebrow/questions to the passengers that sat along with me.

but anyways, i still believe the issue comes down to how the issue is being handled:
car problem ask jkr fix road? really?

That is a well known issue with all the CVT Range of model from Proton recently, thats why Punch now insisted they doing the ECU engine software as well, however some mangkuk in COE shah alam refused and still want to do their own separate development..

Even those CFE engine based model keep on changing their ECU firmware.. as still have problem of of synchronization with the CVT gearbox.

sounds like it is an ECU problem. It might have shifted to higher gears and caused the issue.
So in the end, are you able to climb the steep slope? hmm.gif

I literally shouted "ARE YOU A PENCIL??!!NO!!!YOU'RE A BLOODY GEARBOX!!!!"

Fortunately I'm able to usher the car up the slope. You could imagine me happily driving up a slope until when I meet a car in front moving slowly up the hill & I go no no no no NO NO NO!!! bloody hell.

I could almost hear the gearbox laughing at me & say "Oh a slope. Nope"

31% steep slope also cannot climb, I was wondering how a Preve can climb up to the Genting as I believe some of the Genting slopes are over 31%. some even reached 36%. Write a letter to the old man who is wanting to increase the Proton selling price so Proton can compete with other world class car makers!

Yes, there is one (or several) very steep stretches up the slope of Genting Highlands, surely more than 30%, perhaps around 50%, or even higher. A sharp left turn. I used this steep "inside" turn of this bend when I overtook slower vehicles that were using the gentler slope on the "outside" of the bend.

All the very steep sections up the slope to Genting Highlands are usually on the "inside" of the bend. To manoeuvre through these steep sections from the inside, the vehicle have to make a sharp turn (instead of a wide turn), and the vehicle has to have a powerful engine. Otherwise, the acceleration up the hill will be very lethargic.

With this Proton Preve case however, do note that the vehicle is stuck in crawling traffic jam and is not in motion. Hence, that may explain on the difficulty (or incapability or failure) of it climbing up the hill.

Omfg. Why didn't i realize it. doh.gif

Preve/Suprima is using CVT. The hunting gears is "virtual ratios", it shouldn't affect the torque delivery to the car. Hence the only conclusion is the low end torque that is always missing in the Campro lineup issue. Even for Campro CFE, the turbo only comes in during the mid range, and dips in the higher rev.

From the chinese forum I read, according owner, this happen during traffic jam at the hill road, full passengers (5)in car. After an stop an go, the car not able to climb up again. This was by the owner claimed.

To aid this discussion, This is only 30% inclined slope (close to the reported 31%)
So this is how it looks like in real-life.

The complainant was driving a non-turbo Preve right? a 1.6l NA Preve carrying 5 people, to be exact.

Anyway, if you compare Altis's CVT and Preve's CVT, Altis's is a torque converter, none of those clutch overheat nonsense.

The 'problem' is not on CFE. THe problem with CVT2 with IAFM+ engine. Preve is 13xx kilo. That is why those who bought Preve executive have no idea that is a bad choice although the price is cheap.

should blame it on the road, must ask them to resurface.

this is truly hilarious. what the..... lol!!!

I mean, protong should at least state that "we will look into improving the car/transmission/engine under such situation in near future", rather than just shifting all the blame elsewhere. this is really boleh management. how to improve like that?

so TM, is this how a 120k car should be??? rclxms.gif rclxms.gif rclxms.gif rclxms.gif

Exora CPS (7Seater) NA also has lack of grunt but still can climb on the slope. that because the proven old tech all mighty Slushbox Invecs II Mitsubishi gearbox smile.gif

I drive a Saga FLX SE.

So on certain steep gradients, it tends to struggle a bit, but later can go

Do take note that this is from a stand still condition.

genting, you have the momentum, so you can keep going up

Genting is nowhere as steep as the than Hou temple foothill. It really is not properly designed.
Now I remember, last time I have an incident there also... Myvi manual... Can't climb that slope.. This is situation where it was jam and have to climb bit by bit... If empty road, I think can run up. But not in a jam. So have to leave and gave up the idea of going there that day. I think it's cny time.

actually i don't think it has issues going up the slope of Thean Hou Temple... what looks more like it is that the car got stuck in traffic jam going up it like during Chinese New Year period...

furthermore, the letter was mentioned that a letter to sender previously was dated 19th February 2013 which is co-incidentally around CNY period... that is if Proton CSU is that free and responds that quickly...

maybe, just maybe.. speculating that the owner of the car just got stuck for too long and used the throttle to balance the car on the slopes instead of braking with a car fully loaded with heavy people? (worst case scenario)

furthermore, didn't really mentioned what kind of scenario or problem that happened...if you balance the clutch on a manual transmission all the way up the same road... i guess the clutch will burn up as well...

at least that happened to me before many many years ago at genting highlands on a christmas day...my case was not the slope problem... was the idiot behind the steering wheel...

Yes, there is one (or several) very steep stretches up the slope of Genting Highlands, surely more than 30%, perhaps around 50%, or even higher. A sharp left turn. I used this steep "inside" turn of this bend when I overtook slower vehicles that were using the gentler slope on the "outside" of the bend.

All the very steep sections up the slope to Genting Highlands are usually on the "inside" of the bend. To manoeuvre through these steep sections from the inside, the vehicle have to make a sharp turn (instead of a wide turn), and the vehicle has to have a powerful engine. Otherwise, the acceleration up the hill will be very lethargic.

With this Proton Preve case however, do note that the vehicle is stuck in crawling traffic jam and is not in motion. Hence, that may explain on the difficulty (or incapability or failure) of it climbing up the hill.
*
a complete climb to Genting Highland only averages out to less than 10% gradient.. even the 2 steepest hairpin left on the inside line before reaching Gohtong Jaya (1 not long after the 1st security guard entrance at Genting Sempah) is only about a touch over 20% grade...

the letter does not really tell the complete story though... so, missing out the first piece of the puzzle, the original complaint letter is making people jump to conclusions on what actually happened without being able to fully analyze the problem in nature... or maybe the poster intentionally wanted to post the subsequent ones as the first one will indicate the driver of the car instead...

this is an interesting topic...

Aiyo..where got 30% in genting.pls let us know.like that kancil 660 surely cannot climb ler.

Read properly. Only at the "inside" sections of bends where most cars would have avoided.

If my memory doesn't fail me, the steepest "inside" lines of a left turn are located close to the peak of Genting HIghlands before reaching First World Hotel. Those sections certainly feel very steep to me if you deliberately use those lines. You would feel your engine or gearbox straining, especially if at low speeds when you have just completed negotiating the bend or are just accelerating out of it.

maybe, just maybe.. speculating that the owner of the car just got stuck for too long and used the throttle to balance the car on the slopes instead of braking with a car fully loaded with heavy people? (worst case scenario)

furthermore, didn't really mentioned what kind of scenario or problem that happened...if you balance the clutch on a manual transmission all the way up the same road... i guess the clutch will burn up as well...

This. I think this is likely the case.

After the temple there is several more more of those steep inside lines...but they are nowhere as steep as the ones before gohtong jaya.... That is if my bikes computer don't give me the wrong gradient information when i pass by that section...but as far as i've gone through it a couple of times...it has never exceeded 23% grade before...it is safe though to say that an additional 1 - 2% can be added to that number as i believe the computer does not take barometer readings at split second intervals and it might be a tad steeper than what it thinks it is...

There is also the factor of altitude that you need to take into account after gohtong jaya as you are most likely at a tad over 4000 feet elevation beyond the chinese temple compared to around 2500 feet at the 1st security guard area at genting sempah which causes power drop due to less dense air and pressure going into your combustion chamber...

Genting is nowhere as steep as the than Hou temple foothill.  It really is not properly designed.
Now I remember,  last time I have an incident  there also... Myvi manual... Can't climb that slope..  This is situation  where it was jam and have to climb bit by bit... If empty road,  I think can run up.  But not in a jam.  So have to leave and gave up the idea of going there  that day.  I think it's cny time.
*
I experience once with old manual iswara like clutch didn't engage when attemp to launch at steep slope. Somehow, I manage to got out after rev high (maximize torque) and release the clutch pedal unusually high position (lastly release hand brake). The clutch failed few months after, so I think clutch/gear box wear out could be a factor.

30% is way above of 25% of maximum grade in road design. Even in most cases 10% is the desirable maximum grade.

If it's 50% gradient, it will not apply across the section of the road. Note that it's the "inside" bend of the road during the sharp corner. The road is not maintained at a uniform gradient across the cross section of it. At the sharp bend, just at the inside of the bend, the gradient is higher at that point, and it tapers off when going into the middle of the road. In other words, the car will be at a slanted position at that sharp corner at that particular "inside" sharp bend of the road. From gradient 50% to say 30%.

Most of the steepest streets around the world accessible to vehicles are reported to have slopes with gradients 40% or higher.

before gohtong not that steep. at the guard house maybe a bit of an issue due to the road bumps and you can't carry momentum unless you want to ram through the security checks (or just random glances, not really checking also lol)

the steep ones are definitely past gohtong, around the temple, and the one just before/beside apartments (ria apartment iinm?)

have to use 2nd gear on my manual and it'll have damn huge grunt just to pull my 1.3ton fat ass car up sweat.gif

and yes, air would be a potential issue the higher your car climb as well.

by feel of power is very vague la...

tats why i say if my trip computer dun kid me... then the incline reading should not be that far off... furthermore, bicycles goes up slower than cars.. so the reading should be more accurate than a car ramming through corners...

the bottom parts does have 2 hairpin lefts that rakes up higher gradient than the upper part... maybe you don't feel it driving... but definitely a leg killer on the bike (because we are forced to take the inside emergency line or risk becoming a painting on the wall)...

you car cannot climb genting, is because genting slope too stiff, please ask Mr. Lim bring down the slope to acceptable level.

I am not sure about the inner clip of the curve, but it is very unlikely for a road to be built more than 1:12 ratio. Even hilly road.

Eye sight levelling from ur screen for 30 percent looks like little.
