After discussing the case with a local transmission specialist, he raised the possiblity of some issue with the torque converter (not releasing the clutch properly). So, before going to the final and most expensive step (rebuild), he suggested a last try:

• Added Lubegard Shudder Fix

We didn’t have any apparent shudder, but since it changes the fluid friction characteristics, we should give it a try. We applied the additive and went out for a test ride and… Surprise! The 2-3 delay/hesitation was gone! Im driving the car 2 days since this procedure and it is incredible!

Of course, this solution may not work forever since we don’t know exactly what is wrong inside the transmission. Also, it may not work for everybody since there are multiple possible causes for shift quality issues. But, anyway, it fixed the annoying 2-3 delay/hesitation in my case… and it is a cheap/quick try.

Interesting, thanks for posting the details. One of my 6F35 shifts great. The other one has the 2-3 flare mostly when cold but it can persist.

I have 145k miles on my 2.0 Fusion. At 110k miles I had the severely delayed and harsh 2-3 shift. I did several drain and fills (driving 100 miles between) and it got better, but not perfect. I put in some of that lubegard because of this thread and it is night and day better. It took a couple weeks to get better, but its been fantastic. I have done a couple more drain and fills after adding and its stayed good and I have not needed to add any more.

I used Castrol Transmax as I could not find any of the Motorcraft LV, from what I understand its licensed and/or approved replacement for Mercon LV, 30k miles and several drain and fills later its performing great even with my very heavy foot.

Which Lubegard did you go with? The Shutter fix small tube, Red, or Platinum?

Castrol Transmax does have a licensed version of Mercon LV (and a whole lot of others).
