Knowing UMW Toyota SC like to do bold claim on Toyota WS is an immortal godly oil, did you change gearbox oil at all?

OMG. You should sue them of false claims/advertising.

At most, that oil is 60000km.

I changed mine forcefully on 80000km outside and it was kopi-o grade and smelly. And before that, all the while UMWT SA said it was not needed and for lifetime, and some SA said it was 100000km, no idea who were telling the truth back then... well eventually both were bullshitting.

Now I just go 20000km~40000km gear oil change.

Mine was a Vios 2007. If yours 2011 then it is like 7yrs of 'old oil'. Don't flush. Just gradually replace, together with every oil change until it is pink. For me the gear oil takes around 3 to 4 change to reach the pink color status. Oh and the auto filter I change it along with the gear oil until the oil is pink.

Then now, the oil is back to 'normal', I would do 20000km ATF change, and every alternate 20000km I would change the ATF filter.

I would believe your ATF already losses its ability as lubricant. The cheapest way is to change your ATF before changing any internal parts.

Well even if it was not caused by this, just to add, if you haven't changed the ATF before, it is due. Otherwise you are going for an auto gearbox replacement soon.


[edit] While searching online, originally Toyota ATF WS was rated as 100,000 mile (nothing about immortal or lifetime). With having some failures and reliability issues (notably in may Toyota Tacoma owners), they gradually lower down the claimed 'invincibility' from 100k mile to 80k mile to 60k mile.

While 60k mile is about 97k km, I wouldn't bet on our famous stop-go traffic and hot weather.
