Well! What an easy and interesting job! Did it today. The white thing in the pictures is to do with the gear selector. I put it in Neutral and it was clear of the filler plug.
"Sealed for life. Don't touch". I strongly disagree! I drained the old ATF and only ONE litre came out, and quite brown. !!!! I don't know what damage has already been done, but on a low mileage car (58k) I hope not alot.
The drain plug was an ordinary sump plug with no level checker, so I put exactly 3.5 litres back in.
I'm wondering with such a low level if the torque was filled up, if not it will have less than the stated overall 6 litres.
I'll probably change it again in a few months and will be interested to see if about 3.5 litres comes out.
Anyway one of the reasons why you should change the ATF in a second hand car is because you don't Know, if for some reason, the level is very low as in my discovery today.
Gear changes seem a bit smoother and the noise a bit less but I wasn't having any major problems, but I may have saved it from some in the near future. In my case getting the level exactly right at 60 degrees can't be done, but getting it roughly right compared to extremely low, should be all good.
