JRP:
I don't believe you can add any to it. I did some research for you and here's what I found:
It has a sealed tranny. If it does need some you must take it to a Ford or Lincoln Dealer. It also DOES NOT have a dip stick either.
On guy said, "I remember when I bought my '04 they sent out a bulletin that the factory put the wrong tranny fluid in some of the cars. I had to bring it into the dealer and they drained it and put in the correct fluid." -
So, JRP if you go to the dealer you can ask them to look up the OASIS report on your VIN to see if the tranny was ever changed or affected by wrong fluid.
Also, Fluid & filter is supposed to be good until 100,000 miles. Are you having sluggish shifting? Lurching motion?
From what I learned, it takes a special tool-fitting that will be placed into a fitting on the bottom of the transmission's oil pan. With the fitting in place the tranny fluid can be pumped in with a power pump that connects to that fitting. You pump some oil in then disconnect the pump, When it is full the extra oil will spill out of the fitting. Then you have to use a hand-vacuum pump that will drain any fluid trapped in the system.
It seems very complicated
At the dealers, the machine they use drains the old fluid out and replaces it with the exact same amount of fluid. This means if your fluid level is low (and there is no dipstick to check the level) it will stay low even after service.
So here's a guy that had his '04 changed and said, "Well, with the new clean fluid, my transmission really acted up. It would stay in neutral longer after the lever was put into D5 or D4 and it would not necessarily go into First (1st) gear when it did engage. A few times it would go into a gear too high to start the car moving, and the engine would die. I brought the car back in and asked the technician that serviced the transmission to take it for a test drive. When he returned he put the car up in the air and checked the fluid level. He lowered the car and added first one quart of fluid, then another quart and one half. He then asked me to test drive the car. What a difference! So what really happened was for three years I was driving the car with a 2 1/2 quart deficit of
transmission fluid. On a road trip, the car performed well except for a few of those rough shifts that I had grown accustomed to, and a few times it would stay in neutral after coming to a stop. I just thought it was just a bad transmission design or at best a defective transmission that would fail some day.
But now that it is, really full, I have no more issues."
I hope some of this info is helpful
