Is automatic transmission fluid same to gearbox oil ?

yes

automatic fluid is for automatic transmission ma....

Gearbox oil is for Manual transmission

where got same

is automatic transmission a gearbox as well? or maybe it's my misinterpretation due to mandarin/cantonese naming which generally just call it "gearbox oil" regardless it being AT or MT

No.. even with chinese naming, they do differentiate AT from MT since they are both distinctively different oils. Even with chinese they would say 'Auto Gearbox oil' for AT and just 'Gearbox oil' for MT. Whatever language is used, the AT oil is not the same as MT oil.

+1

Totally different. ATF is more towards hydraulic oil grade and viscosity.
Manual gear oil normally from 75w or 80w to 90.

is the hydraulic oil inside the viscous clutch different from the lubrication oil in the gearbox? this is for AT

ATF is again different from hydraulic fluid, just mentioned that the viscosity is different from manual gear oil and is lighter and closer like hydraulic fluid.....

jus let us know what car u drive and we can tell u which is suitable

There is difference between auto, manual, CVT and twin clutch i think.

Putting the wrong one is instant bye bye

well myself (and most of the mechanics) just call it "gearbox oil" (or gearbox, "ngar xiong/ya xiang" so to speak), until you need to differenciate it then you just add AT or MT.

obviously ATF already clearly stated it is for AT. gearbox oil on the other hand, i dont recall "gearbox" being distinctly used for MT, as people just add "hand" into gearbox if you want to specify it being MT.

and yes, you and vr2turbo are both corrent that AT oil/fluid and MT oil/fluid are not the same, which i am not saying they are either, i am merely referring to the vague naming of "gearbox oil"

so let me get this straight.

either way, automatic transmission fluid is just another word for auto gearbox oil ?

if you put it that way, i will be even more affirm on the answer that i have provided.

sifus please do correct me if i am mistaken again

Yes, you can put it this way as long as mention is auto gear box, as manual and auto gear box uses different oil.
Auto transmission is also call an auto gearbox.

Bro. rcracer is also correct as CVT gear box again uses different oil as in CVT gear oil and also DSG boxes....

yeap this too.

so to TS:
if you really want an absolute clear cut answer, better provide your car make/model, and its transmission system, then we can further advise as needed

Yup, correct...

Last time, there were cases of CVT gear box when newly launched, they put in ATF then gear box died....

got it guys! thanks a lot!

its a myvi 2009 auto

i think myvi normal ATF (or auto gearbox oil ) will do, as it doesn't have special transmission type such as CVT/DSG

What is the mileage done? atf not changed before?

dextron III for myvi, mineral and synthetic based.

just use synthetic based...it wont cost so much

Is it? I thought usually synthetic will cost much more.
But if doing oil pan atf change, isn't it better to use back the same brand and type as you are just mixing the atf up, unless you are doing a flush?

Guys, My ATF tends to overheat. if I install a ATF cooler, can i install the same oil and pressure sensor, just like those oil coolers? or need to modify the fittings? Hope Sifu here can enlighten me.

Any good durable ATF would recommend? Driving a old waja

perhaps can try out lubegard platinum before installing additional coolers, if it resolves your problem, thats the end of it. if it doesnt, you just waste ~rm100, not too expensive compared to going through permanent hardware changes/mods which usually cost more, and may not resolve your issue.

Yes can, but need workshop that really know what they are doing with those fitting. If money not a option then go for steel tubing -custom made line from the tran to the radiator to the atf cooler and back to tran. Install a fan too. For the ATF fluid, i think it better to use back the ori ATF fluid because the tran already old. Changing new one might lead to abnormal gearbox issue. (in some cases only)

just add one additional cooler...few hundreds.

and when u meant overheat.....how u know its overheat?

^

exactly.

Hunch?. Cause during cold start etc it's ok. After spirited drive etc, there's a delay when I shift from N to D. Delay is like close to 2 second before the car engages gear. Some of my friends told me it's the transmission overheat or most likely insufficient ATF fluid. When I let the car cool down the next day it's ok till I drive the car hard.

Yes. I heard need to pull out the transmission cover and fabricate a port. Definitely use steel braided hose since it's high pressure. As I'm well aware the transmission peak working temp is less than 110 degrees. anything above, will result in ATF fluid being burn off. Thus, I was hoping if anyone did attempt to install sensors to tap the temperature. It would be great to know we're not stressing the transmission too much

Yes. Also thinking an option to install fan. But, standard fans are too big to be fitted on the cooler. May need to go with passive cooling since there isn't much space in under the hood. Hence I need to know the temperature.

just remove d atf cooling hose from radiator to external cooler. done... dun need so complicated

some ppl do in this way (either one)

atf -> radiator -> external cooler -> back to AT

atf -> external cooler -> radiator -> back to AT

atf -> external cooler -> back to AT

which one is better is depends on individual

No harm as an external cooler is always better.
Try checking if Penzzoil Multi Vehicle ATF is compatible with your current atf. A few of my Honda friends have switched over because the Honda atf prices have sky rocketed. Penzzoil Multi Vehicle ATF is FS atf, and is quite cheap.

Added on December 28, 2011, 3:34 pmLooks like sign of overheating, but do you need steel braided hose? Your normal hoses are rubber ones, right?
Even my engine oil cooler hoses are the rubber type, and they are running hotter then the atf.....

Thanks guys. Just got my ATF cooler. It's not cooling the ATF as I thought. It's to cool the return radiator water to auto gearbox as brother Kenny mentioned. They told me to install.

atf -> radiator -> external cooler -> back to AT

Want to try

atf -> external cooler -> back to AT

But not sure if the auto transmission got pump to drive the radiator. Brother Kenny. Can help to confirm?

in our hot country better to bypass radiator completely, in cold country it serves double purpose to also warm the ATF.
Besides to me it's stupid to still use the radiator one because lets say traffic jam and the water is 80-90 degrees but the AT is only 60 degrees, it'll start heating the oil instead or the external cooler is cooling the radiator.

Plus the longer the lines the higher chance of leakage and i don't like the fact there is chance if there is a leak in the radiator one, water can get into the GB and ruin it.

Did you try to find out the cause of overheating or not first?

I whack my car too hard. Huhu.

If run external standalone cooler, I think need to make sure the placement is correct else it will suck in hot air. The radiator is tad small. Seller recommends me to install fan.

Was about to say you have spirited drive......

Many cars actually don't have an atf cooler, so I think fitting one will be good.
The only thing is the place to install it. If can face the front, I don't think you need the fan....

just make simple bracket and mount in front of radiator, no need fan, fan at high speed become a restriction as long ambient is cooler than the gb cooling willl take place

thats why la, i whack my car hard also, time to time maintain red line 6-7k rpm, also no problem shifting etc.

thats why i recommended lubegard, maybe it works for him, maybe not, however its not something permanent, and the cost isnt exactly a few hundred or so to speak.

thanks folks, my car ar... *sigh* still along list of upgrades... Next might be oil coolers...

anyone here know how to install OCT on campro?? got two holes on top of the rocker cover. which to connect? the left one I put a small breather.

Yup, some mentioned using lubegard does help too......

Added on December 29, 2011, 2:27 pmWhy you need oil cooler, you have no turbo?

This post has been edited by vr2turbo: Dec 29 2011, 02:27 PM

hence the recommendation to try, i was also specific that it may or may not help

Yup, more slippery runs cooler also......

Actually......

OCT=oil catch tank?

yeap.. But nevermind, i've installed it already.

oil cooler fits NA and Turbo

it doesnt mean u dun need external oil cooler if u r on NA

my2cents

If use in the track, maybe need. Normal use no need loh!
In turbo, the oil gets very very hot, after passing through the turbine bearings......

yes...it all depends on driving behavior

normal car normal use for sure dun need

Normal use also, atf cooler more useful......

Just don't too oversize with the oil cooler, too big is not always good. your pump may not support such load. Use OEM halfcut is a good choice, exp - GSR oil cooler.

got topic before.....

http://forum.lowyat.net/topic/1115799/all

sudah angkat. Haven't install.. now cracking my head where to place the cooler. There's little space in my engine compartment. huhu

If u have small space, u should pick finned tube atf cooler.. Normally available in honda car, and go any halfcut shop u will find it. Few of my friend are using it and ok till now. (for mid power user) here the picture link below.

atf cooler honda

this normally for power steering fluid

seldom saw in in ATF, maybe only in honda? im not sure

if really wanna use this kind of cooler, then for sure cannot bypass the radiator cooling way....otherwise sure overheat

Yup, in my mitsu for power steering only. Cooler more like radiator type.....

hello, i'm driving saga 1.5 auto (1991), last week i realize the gear change is bit laggy from D= gear 1 to 2 is 2700RPM , while 2 to 3 is 2500, then i change the ATF and filter - Castrol Dex II. But the problem still exist( gear change lag).??
Is it my gearbox using Dex II? (i ask at spares shop and they give me that).. and I do my research on net and found that my car requires SP II Atf fluid.. is it rite or it for newer Mitsu Gearbox ??

do a proper ATF flushing, then you can give semi/full syntheticsynthetic ATF fluid (so long it is compatible) a try. (all this also not cheap, could be between rm200-400+, but still cheaper than servicing/overhauling/replacing the whole gear box)

if it does not help, i am afraid you may need to service your gear box

There's one cable connected with your accelerator cable to the throttle body. adjust and play around with the nut, it will affect your gear change response.

i've never seen Honda atf cooler like this..

most honda cars dont have psf cooler..except the facelift civic fd 1.8 due to lot of complain on power steering hose, pump n rack problems.

It's an old auto gb, u can even use Castrol TQ.
DEXII & III doesn't matter, all will work.

scorgio.. Thanks

Hi all,

does anyone know whether toyota vios atf oil filter need replacement or not?
I've read in some forum they said vios don't have a atf oil filter. Is this true?
Another thing is it necessary to flush the atf before changing new atf? Does it give big difference in performance?
Thanks a lot.

if the fluid drained out is very dirty, then need to flush once or twice. otherwise just replace

vios filter not sure, normally need to dismantle the oil pan.its inside. paper type need replacement, some are rewashable

Any recommended ATF cooler brand, workshop to install it and ATF brand for old perdana auto gear box? I heard use back mitsubishi diamond queen SP3.

caltex ATF-J + lubegard platinum. if solve your problem, can forget about ATF cooler

What is the market selling price for them?

lubegard plat ~rm9x
caltex atf-j (from their petrol stations) are rm36/liter bottles
