    Are you suggesting I should not change it to Micron V?

    Just put in good quality transmission fluid that meets the manufactures specifications whether it is synthetic or not. It is really up to you if you want to spend the extra money on the synthetic over regular transmission fluid. In the winter you will get a little better mileage with the synthetic over regular fluid.

    ALS, you have made the winning point. Use a maintenance plan like you suggest. Keep it simple. Don't overdo it. It's a small tried and true investment to insure your expensivd transmission doesn't fail. Transmissions are finicky. It doesn't help the OP much however.True.

    I think I'm gonna give this car a run for it and try replacing the filter Saturday. Along with micron v to ensure the best possible outcome.

    Good news. Changed the filter (broke 3 bolts) but got the pan off and changed the oil back to mercon v and its back to normal! Thanks for all the advice! :)

    How dirty was the filter?
    Also be sure you know the proper way to check your trans fluid level. Some vehicles have different way of doing so.
    Keep us posted.

    Back when I still had an Escape, the members there figured out that by doing a drain and fill 3 times, you ended up dumping out 93 or some other high percentage of the total volume of old fluid. Which was important as that transmission had a tendency to turf itself before 100k miles if you weren't religious about changing it out.

    What I did was drop the pan and then do the flush into a bucket trick. Seemed to work very well.

    Checking the fill on the oil? I pull the dipstick and check it based on the fluid temp (it has 20C and 85C). Are you saying this could not be the case?

    The next day I found slipping again, I did just as I said above and the fluid turned out to be about 1/2Q low. After filling (it is a tad over on the dip stick) this thing runs like a dream! I am getting much better FE than originally still. Hitting 48MPG @ 48MPH... Previously I was lucky to get 40MPG at that speed.

    I will keep checking and give an update in about a week.

    Many different companies have different procedures for checking the fluid level on the dipstick and it may be in your owner's manual.
    Glad you're experiencing better mileage and you hope you can keep it up!

    Thank you. I will reference the manual!

    The last few days have been good tests. I felt it was worse in the cold. So far it has been great. So great I have been getting quite a bit higher numbers (+8%) to work since last time it was 32°.

    Cheers!
