Hi mazda owners,

I am planning to buy mazda 6 and the sc told me that you need to change the gear box oil every 30 to 40k km due to our weather here when I ask about the lifetime atf for all the, new mazda skyactive car... But he advice to change outside coz the sc won't change for you and will void warranty. Can someone confirm this please? Please advice your experience with any new mazda sky active without changing your gear box/atf oil? How long you have drive and any issues?

BTW, it is true fact that if you change your ATF outside your gearbox warranty will be voided. You just pray either gearbox no issue during the 100k or 5 years warranty period.

The Mazda technician i knew feedback to me that ATF oil got different color for different batch Mazda, so if your outside mechanic is smart they will need to get the original same color ATF to prevent any suspicion during warranty claim.

If unlucky, you can either do full overhaul/service of the gearbox or get half-cut replacement from Japan (which i heard is hot cake in aftermarket nowadays, very fast sell out)

Mazda have 5 years warranty.

My advice is to change only after warranty. Do not give Mazda excuses to void your car's warranty. Even though it might not be gearbox related issue but they have the right to void the warranty as written in the terms.

Their gearbox are sealed in vacuum from factory. The claim no need to change for lifetime of the car. Some people argue 5 years and some says until the car die.

As for me, I have not changed the ATF for 5 years. Planning to get it changed after warranty which is coming soon.

Sad to say, no, gearbox are not fully sealed. Even the most luxury/advance gearbox also got breathing hole or valves to ventilate the hot temperature pressure release from gearbox. So when you have breathing hole or valves this is not 100% sealed.

Most recent workshop i went already use vacuum machine, for old engine oil or atf suction. So recommended to perform atf using this way

Huh? Do you mean ATF oil change machine. That is long time technology, even 20 years back already got. The problem is if your ATF oil is too long time no change or very dirty and you use this machine it will cause your body valve & gearbox even faster to gg, the concept is forcing the old oil out from the gearbox and use the machine so call filter system to clean and provide fresh ATF oil in. Weakness - More ATF oil need to use & if your gearbox got a lot of sludge or metal debris hanging around the machine will only cause more harm if all those thing stuck at body valve or clog the filter inside.

The best way for gearbox oil change is open up the below oil pan, clean it, change the gearbox filter/strainer (if available) before replenish with new ATF oil. You will see a lot of metal debris hanging below the oil pan and attach on the magnet area, even you open the oil drain plug below all those metal debris wont be able to release out and just imagine using the oil change machine and the metal debris start moving around (not all will attach on the magnet).

My previous mechanic got this thingy at his shop and now just throw on the side. Until today only heard use in Ford or certain vehicle, but Mazda no need. You can just change using normal way. Plenty of youtube videos about changing ATF on skyactive gearbox. The traditional way is still more better, less risk & less ATF oil to use.

I think there is a procedure to change oil if you have not change it for a VERY long time. I think suppose to drain partial and fill it up as opposed to flushing entirely.
Mechanics stackexchange - partial replacement instead of flushing for cars that have not replace ATF

If this happens usually already neglected for far too long. The ATF oil already thickens and the gearbox already suit with the thicker oil and if you change all the ATF oil in one time the body valve or TCU might not be able to direct adapt to the change of ATF oil will cause issues. Nowadays most modern gearbox already can reset this adaptation, thus why you will hear after oil change need to reset ECU/TCU on modern cars due to this reason.

If u follow manufacturer recommendation ie. lifetime or 100k km, ur gb don't kaput, the solenoids also kaput.

That's what happened to my brother's Forester, he changed the CVTF at 100k km as per recommendation. Then at 130k km, 6 error lights pop-up. Subaru SC scanned the fault code & recommend
1. try with another CVTF drain & fill - RM700
2. replace valvebody (Subaru do not sell the solenoids separately officially) - RM6000

Then we started doing research online. We saw some users mentioned the CVTF change should be done at 60k interval or 45k interval (frequent spirited driving), to reduce risk of failure of solenoids. So u see, the manufacturer recommendation was designed for ur gb to suffer some damage right after warranty period ended.

2. replace valvebody (Subaru do not sell the solenoids separately officially) - RM6000

FYI, solenoids usually are sold by aftermarket sellers.
These spares Subaru did not sell it officially as they prefer to sell the bigger piece (bodyvalve) due to higher profit and less headache/risk.

Simple google, shopee & even lazada also got seller selling it already and even Auto Sommet from KL (one of the Official seller of original Subaru parts) also got source, what you will need is to get a gearbox specialist to identify which solenoids is the culprit.
If you met the correct specialist/mechanic, you will save at least 50% from what official SC quoted. In Subaru Forester Malaysia Group some even DIY and share their stories in FB, the cost is just few hundred for the solenoid.. laugh.gif

BTW, already got plenty of bodyvalve recon & used gearbox in market (half-cut from Japan) for alternate lower cost options.

Now in group if spirited driver we encourage to change even earlier, even me myself change every 30k for CVT oil for my Xv (Now almost 195k still original gearbox) Besides that, the CVT filter/strainer is also an important part to take note. We noticed a lot of failure from previous owners reported after 150k due to not aware of this part importance to change or service it. Usually we recommend to change it around 100k for the CVT filter/strainer.

Subaru owner also had plenty of cvt issues? What is the recommended from Subaru for cvt filter? Iinm mostly manufacturers not put it in for replacement at a shorter intervals and car owners just follow it. Or the CVT gb will getting issues once hit some high mileage?
*
Depending on ownership and driving behavior, if met the correct mechanic after 5th year or 100k warranty will recommend to change the CVT Strainer/Filter. Even the Subaru specialist SBR Technic recommend owners to change it early by 4th year 80k. If you change this early usually no issues, some of the owners already way over 200~300k with every 30~40k CVT oil change.

From my understanding official SC did not list this CVT strainer/filter to change during the 5 year or 100k service interval, mostly only by owner request after warranty finish. I did my change at 110k but from outside mechanic, nowadays got OEM Thailand/Taiwan CVT filter/strainer to choose in market.

I am surprised if they are not equipped with the skills of changing the ATF.

The way I see it is they like to harp on the ATF being sealed for life but they don't have the skills to change the fluid if the customer requesting for whatever reason.

I think they could earn some extra dough if they were to provide ATF fuild change, I am sure they will be up skill with the know how and proper procedure and sop to do so properly than outside pomen.

Eg like in proton they dont mind changing for you earlier  if requested for as long you paying for it. Usually they ask why are you doing this but eventually they still change it for you.

Also, does this lifetime fluid also applicable to manual mazda?

They can change the ATF oil for you but warranty void for the gearbox. Already confirm with Mazda technician, if you insist to change it within 5 years or 100k they will ask you to sign a document mention that you knew about the warranty void. So better just go out.

Tumpang ask, any idea how much it cost to change condenser for cx5? Was quoted rm880 for condenser itself and rm300 for labour, not yet include other aircond service cost, is the price reasonable?
*
If you cheapskate ask for local, Thailand or China made condenser. So many aftermarket stuff nowadays just you want take risk of the quality. Some of them may offer 1 year warranty, so would be better to get 1 with it.

Bro, your view for oem engine mounting vs original. Price almost 1/3 original price. If it Honda, many oem made in Thai. Ok or just meh?
*
You got 1/3 from original price, so dont expect so high. If lifespan last more than half from your current original part consider worth or cover the savings already.
