2004 Lincoln Aviator Q&A
2004 Lincoln Aviator Question: trans fluid
You actually do not fill from the drain plug. You fill into the fill plug. The fill plug takes a special service tool fitting that goes in to allow fluid to be "injected" in little by little. Some shops use this adapter with a power steering fluid exchange machine to add fluid (using Mercon V fluid of course) in order to accelerate this process. The transmission is full when at the fill hole fluid starts to overflow. - DaveJHM
Where is the dipstick.
The tranny has been serviced and fluid changed. At times it shifts normal, but ither times it is late shifting, hard shifting or feels like I am "towing" something.
