mineral replace every 30k km, if using fully syn (like
shell atf) can last until how many km ?
I think for best performance better change every 20k km. I don't know about traffic in your area, but in Klang Valley, anyone who commutes to work in the morning and evening traffic should classify their cars as "extreme environment" and service their cars more regularly.
Even though a car's mileage may be low because the car hardly moves in a jam but the engine is still turning, so is the torque converter.
I think a forumer is selling fully synthetic Korean car atf at mineral atf prices, maybe you can pujuk your SC to switch to this for you. Maybe have to pay a "corkage" fee

i not sure my ATF synthetic o mineral(caltex brand)...but i do change it every 20k...throttle body clean??/ i think i need consult SC.....heard from american, they asked me drain n flush transmission....i dunno wat that means oso...
Basically, flushing out the GB means draining out the old atf, then use new atf to flush out the remainder of the old atf, meaning new atf goes in, mixes with the remainder of the old atf, then flush out. Repeat a few times until the atf is clear. Normally will use around double or more of the GB's fluid capacity's worth of atf. Quite costly but cheaper than a rebuild.
As for cleaning of TB, it's due to the fact that the GB and engine have sensors that are read by the ECU and if the sensors are dirty they may give a wrong reading and affect the engine-GB synergy.
I suggest changing over to synthetic atf first then see how it goes. You can buy ThreeBond throttle body foam and clean the TB yourself.
After that, if still not satisfied, try adding a Fire Storm ignition booster
