I have a 2015 Mustang Gt Auto. I am currently tuned by Wengerd Performance.
My problem is that when I am wot and shift from 3rd to 4th the car shifts into 4th, waits half a second, then shifts into 5th. It will then shift into 4th again after a few seconds or so. It only happens when I shift above 7k rpm (redline set to 7,800). I am in sport mode using paddle shifters so the car should not be shifting (unless when rpm gets too low).
The 1-2 shift and 2-3 shift is fine. Haven?t done wot 4-5 or 5-6 above 7k rpm.
Ive been going back and forth with my tuner and they can?t figure out the issue, so I thought I would post on here. Any help I could pass along to the tuner would be much appreciated!
I will attach logs when I get home.
