Hi I've been reading for a while on the forums and can't find a definitive answer for my case. I own a 2013 CX5 GT 2.0 Skyactive AWD and it just passes the 100k mile mark. I bought it with 95k miles (low mileage in my country) and I don't know if it ever has had its transmission oil or filter. So I want to get that done but should I do a drain and fill or go ahead and change the filter also? I'm getting mixed answers on this. And how many Liters of oil will I need in each case. I am feeling the transmission could be smoother on gear changes, please let me know and thAnk you so much for your answers!
