I have a 2017 pathfinder, my grandson said he’d change my oil so i said sure, go for it. Well he drained the transmission fluid and not the oil. Now I’m replacing the fluid with the dealer bought CVT fluid. Problem is there’s no dipstick. Is there anyway to do this without going under to the fill hole? This is all new to me after been working on autos all my life. I’m at a loss.
