CVT or Standard AT?

The problem is they added torque converter to the cvt w/c is another system that might break down.

The CVT part just changes the ratios. It still needs something to disconnect the tranny from the engine when it is not moving in D.

The notorious Honda CVT used clutches. The new one uses a torque converter.

Ever since I've got to drive a CVT, I'll always go with one provided there's the option.

No shift shocks and required RPM's to change gears sealed the deal for me on the Lancer.

The failing clutches are the number one reason for the shock and judder experiences.

While I was having my Lancer's AT replaced around 4 years ago the City CVT beside me was having its clutch pack replaced. I guess the parts are available. Repairs and/or surplus replacements are a hit and miss affair though.

Take very good care of your trannies ;)

Ah okay pala my available parts pala Sa atin ang CVT.

I trust a torque converter a hell of a lot more than a dry clutch pack. The slippage is absorbed by the transmission fluid, rather than the clutches. Which makes the clutches last longer (just keep changing the fluid).

Old CVT parts are, as far as I know, surplus. They're supposed to be maintenance free, so the supplier doesn't sell pieces.. just whole assemblies. But if they sell clutch packs already, then that makes buying a secondhand first-gen Jazz CVT a good deal... incredible economy, smooth running.

Ford, by the way, supposedly sells clutch packs for the Fiesta dual clutch transmission... which also uses "dry" clutches.

A car with CVT will likely be more fuel efficient as it will continuously match the power band and/or the efficiency of the engine at any given speed (within limits of the car, of course). As for performance, all else being equal, a car equipped with CVT will out-accelerate an equivalent A/T car because of this continuous and efficient energy transfer. Of course, assuming that the PCM electronics can be set or is smart enough to distinguish between an eco run and a sport run.

As for reliability, I think it's safe to assume that most modern CVTs that came out in the last 5 or so years are typically more reliable compared to models that came out 10-15 years ago. I keep reading about those older CVTs starting to exhibit issues like noise, judder, sliding or problems typically associated with the CVT belt. Wear and tear is especially accelerated if the transmission wasn't taken cared of properly or if the owner used the wrong transmission fluid kind or type (which is a common mistake).

Traditional A/Ts on the other hand has had time to mature so if you really take good care of it, it may very well last the whole life of the car without issues.

Says it all (y)

The clutch packs might've been surplus. Wasn't paying attention too much. The filter I'm sure was bnew because the owner had to run off and buy it himself. When they were done they poured in 80 peso bottles of generic ATF. Hello repeat customer

Hahahaha! Like refilling a diesel truck's tank with the fuel drained from it after having to replace a clogged fuel pump.

"define better."

by my experience as an ordinary diver,
"it does not matter, CVT or regular AT."
i just step on the gas and my car moves.
i step on the break if i need it to slow down or stop.

i have a MT.
the trans box has not shown any issue, even after more than 140K km of non-maintenance.
i replaced the trans oil only once, after ondoy.

[mustard]

CVT i think easy to maintain.

yespo.
just like AT, i bring my car to the maintenance shop and let the guys do the greasy work.
while waiting, i relax and sip some coffee in their waiting lounge.
heh heh heh.

back in the day, we would change our MT's transmission oil by ourselves. it was easy.
today, medyo mabusisi na... it's not as easy as yesterdecades' drain-and-replace procedure.

[oj88]

I disagree. Traditional A/T and CVT are maintained practically the same way.... drain and fill.

CVTs are just much less reliable overall so they may benefit from more pampering in terms of operational usage and maintenance, compared to a traditional A/T.

[shadow]

Parehas lang. Just do the scheduled maintanance.

IMHO, the biggest potential hassle from a CVT is if the casa claims it changed the CVT fluid but, in truth, didn't really do it.

And it happens a lot more often than people think.

amen.
they said they cleaned and adjusted my brakes.
when i went to my suking banawe boys, the next day... "ser, parang ngayon lang na-buksan ito (since new)". napaka-dumi sa loob!
