Alright I've been fighting this for almost 2 months so I'll make a post.
My 2018 coyote F150 will shift exactly as commanded 1st-5th, but once it gets into 6th it'll shift into 7th at about 6700 rpm. If I stay in it, it'll down shift back to 6th and than back to 7th, and still before I want it too. I feel like I've tried everything possible.
I've even commanded it to shift into 7th through 10th at 10,000RPM and the appropriate OSS rpms for 10,000rpm to try to keep it from going into 7th. No luck, still 6700rpm
Here is a tune and a couple of log files.
Please let me know if you see anything that would cause this issue. I may have tried it haha
