Where do I put ATF fluid in a 2003 TL? The dipstick hold is quite small. Do I need a special funnel?

 

Usually you'll need a funnel to fill ATF.

 

uh, okay
well, welcome to the boards. hopefully you've explored your TL around a little more before posting this here. i suggest you to not pour it in your dipstick.. i hope you were jus kidding about that. but anywho, on with your question.

Welcome to the forum. Click on the link above. Our cars have a ATF fill hole.

 

It really isn't that hard. Once you've done it, it's quicker than changing your oil.
