On ATF Lifetime thing, don't follow what SC practises or what the owners' manual says, including the European's.

As an owner with no abundunce of $$$, one should consider the physics/or chemistry of 'ATF Lifetime' and NOT the loyar burok aspect of fake Lifetime.

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.

The issues under Bermaz, they put 100k km capped warranty mileage. Just change atf outside every 30k-40k km. The shop using a vacuum machine.

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.

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.

My Mazda is approaching 9 years old now with original ATF.
After hearing all these, I will change the oil and filter soon.

Please so. Once the gb had issues, there's no turning back via atf change only

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.

I came from CX5 FB group. There are owners who die2 believe the Bermaz/Mazda words that is atf seal for life. And they got issues gb broke right after 100k km, iinm the owner had gb problem at 120k km, another at 150k km, never had gb atf replace. They fight with Bermaz cz according to them, never missed any service at SC. Bermaz straight away covering their s by said no more warranty cz >100k km. And many others with ATF change (just regular atf change no fancy2 flushing etc), never had gb issues above 100k km, some already meet 200k km. So I will follow the 2nd group of people cz cars is non regular change items in my case, and I will superbly reluctant to spend thousands for gb replacement if it dead. Normal torque converter auto repair easily cost rm2.5k - 5k depending on model. 6 gear automatic is expansive.

And to my surprise, there are also cx5 owner who claim new gb under warranty cz their gb dead at 70k -80k, luckily still under warranty. According to them, never had atf change. Come join cx5 fb group

Yes i agree with changing. I don't believe lifetime. Their lifetime potentially jz 5 years. Like proton power window lifetime warranty is 10 years. Jz commenting for the person that never change for 9 years. Cause my mom unser never change atf for 12 yrs. Once change, then gg d. I don't think my mom should not change, i jz feel should change partially.

See you all dare to replace fully or not lo. For me i rather change little by little. I also planning to replace my mazda 6 atf after 30-40k outside. But see how first la. My car is weekend family car. Drive very little.

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.

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?
