Hello everyone. I'm new to the forum and I do apologise if the topic already exists, but I have performed a search and it returned 0 topics. So back to the question. I have a 2016 GS300h and was just wondering if the transmission oil has to be changed at any point. I was searching a lot in internet and nothing says that eCVT oil has to be changed at xxxxxxx miles. Does anyone has an idea about it ? Thanks
