I saw a video on Youtube, a man from Malaysia (maybe), changed his WS with T-IV at 120k km. I asked him if his vehicle ok then he said it is ok. changed 2 time after video and reached more than 210k km without issue!
Tks bro.
My Toyota vehicle is same as Yaris and i've just changed OEM fluid with Castrol Transmax ATF Dex/Merc Multivehicle, which is claimed to complicable with Toyota WS vehicle. Is mixing OEM fluid and Non-OEM fluid (Castrol) is fine?
I hope it works well. I just read another thread mentioning about using Total LV Fluid causing noise. Mine is smooth after changing, no problem till now
I just change my Toyota's transmission oil with Castrol Transmax ATF Dex/Merc Multivehicle (which is claimed to meet Toyota WS requirement). I read ur thread and suddenly worried about my vehicle :(
