Assalamoalaikum. I am planning to change my toyota vitz 2017 CVT transmission oil. I am planning to use kixx cvtf oil. My first question is that kixx is reliable and safe for toyota vitz? And secondly, is cvt calibration necessary after CVT oil change? And if someone is from Hyderabad, Sindh can he please tell me a workshop which does oil change and calibration properly?
