6 speed ford/GM designed 6F35. It has the updated valve body.
So it had a full fluid swap during the warranty valve body fix, approx 33k miles. I had a full fluid swap done at 120k and I did a drain and fill around 160k because I was worried that MaxLife atf wasn’t the right stuff. I know now that it’s fine. I have enough Mercon LV to do another drain and fill.
Thoughts on when I should do the next drain and fill? Ford claimed 150k for the original fill.
Transmission is shifting fine, no strange behavior noted.
