Can CVT vechicles use ATF oil?

[Neotan]

Hi,

 

It may seem obvious but I counter-check this with a mechanic, who is popular with Toyota Vios members, and he claims that ATF can be used for Toyota CVT cars and this claim is backed up by the AD's mechanics. I have serious doubts about this and just want to hear from bros driving Toyota CVT cars. Thanks

wat kinda noob qn is tat?

 

CVT = auto trans.

 

auto trans not = engine.

 

auto trans uses ATF fluid

 

engine uses engine oil

 

ATF fluid not = ATF fluid.

I believe TS is asking about dangers of using non-cvt ATF on cvt cars.

[Watwheels]

ATF is nonetheless gearbox oil. Its purpose is to lubricate and reduce heat from friction of the moving gears.

 

I had worked with a lot of gearboxes in the industry. It's down to application, ie heavy duty or light duty, and viscosity.

 

For CVT or Torque converter type of transmission gearbox, they can use the same type of ATF with no problems. It's not like using regular ATF on CVT gearbox will damage it indefinitely.

 

For CVT is pulley type of transmitting power, it's still connected to a set of gears. Just like torque converter only that it's drum type filled with oil. Gearbox is still the same.

Read your manual. It should be clearly indicated what kind of oil to be used for your gearbox.

Since we are at this topic...

 

Is the 'droning' sound from CVT due to the metal belts? If so, then, doesn't that mean that if one use a 'proper' CVT ATF oil will reduce said 'noise' or friction?

[Slowmo]

The point is, even if manual states use CVT ATF... based from another topic started here, I doubt toyota cvt car owners can change to cvt atf at their local ADs

I think u misunderstood how CVT works. The pulley and belt is a means of power transmission just like a torque converter. It's connected to the gearbox not built inside it.

 

U do some reading u'll understand. Here's a link:

The droning u described is the characteristics of the CVT. Changing ATF dun change anything.

Not sure if there is a specific ATF from Toyota for their CVT; like Honda.

 

Mitsubishi clearly states that use their Diaqueen III for CVT so there is no issue, widely available.

I think the TS got a PI car unless it is a Prius

Coz at the moment all BM's AT cars are 4-6AT except Prius

Toyota PI cars normally give jap manual so not easy to interprete

The Super CVT uses Toyota CVT Fluid TC. (part number 08886-02105)

Regular Toyota AT uses T-IV for most current applications.

i beg to differ. if all fluid the same then why bother creating a different one? a CVT fluid is meant for CVT cause the friction modifiers are different and will cause different slipping and shift feel. putting regualr ATF like toyota typeIV in will change things. might be better or worse, but why mess with it if the correct fluid is specified.

hi bro,

 

so it short(summary); Toyota ATF able to use for CVT ?

 

i drive rav4; running on CVT so going to replace my fluid so now blur dont know whattype of fulid should be use on my ride.

 

thanks

[Trex101]

In short no, CVT fluid for CVT while ATF for auto transmission.

Best is check your car's manual which usually states what type and brand of CVT fluid for your ride.

[Horizoner]

manual can be inaccurate in some cases.

 

If i remember correctly, Honda recommended ATF for Fit/Jazz CVT. However, many Fit/Jazz faced CVT problems and Honda introduced the CVT/HMMF for their cvt. Best is to check with authorised workshop who receive the updates from manufacturer.

That may or maybe not due to ATF, in the EK ver CVT, I encountered speed could not increase after 120kph though rpm showed eng ram up & down 3-4k rpm.Though could not proved what was the casued, whole CVT box was changed FOC (under warr org costs $4K).

Service was done all the way by KM and ATF changed every 20Kkm at that time. Recalled that time the CVT ATF was same red colour as our auto ATF but not sure what was the content like viscosity etc.
