Thanks Ranger,

I have been learning from you a lot.

I agree with you that removing the pan is a good thing to do. What I wanted to say was that when dropping the pan, if it is empty (after sucking ATF from the dipstick tube by syphoning), your mess will be much smaller... I don't know where the filler hole goes in a 4T80E, but if it goes only to the side, not to the bottom, it will not work as you said...

Oh well, anyway, thank you very much.
