I am planning on doing a transmission fluid change in my 2020 forte ex with the ivt transmission, I went to a dealer and bought 8 quarts of the oem SP-CVT1 fluid because the trans holds 7.1 quarts. I was curious as how to change the fluid. I can see that there is a drain plug and a fill plug, but I didn’t know if there was any special procedure when I change the fluid. I hope it’s just a simple drain and fill but didn’t know if I needed anything special to do it. Any input on an official way to do this would be greatly appreciated. Thx
