Hi Folks,

The issue in the Log 46 and video 42/46 shows the problem between 5th and 6th gear change and he adjusted it some and it got better in the 2nd adjustment in log/video 47 but still has a slight issue.
Its only 5th to 6th gear the problem happens 2 out of 3 times
Now all other shifts in the mustang 2019 gt 5.0 are fine and it has the procharger HO kit and tune so you know what its running
Maybe someone here has seen this issue and can give some insight to the issue.

If you look at the short videos its very easy to see it drop throttle or something

This all started once the new update was flashed to the transmission and increased the tq output he said.

The old original tune had shift problems as well so this was better except the 5th to 6th gear change issues.

Any help will be appreciated Thanks folks

I think the 10R80 new trans can trigger throttle drop if slip is detected.
How old are your steels/clutches?

I can tell you for sure the 6R80 will let you blast unlimited RPM if it slips the 2/3 shift especially if you rely on trans for rev limit w ECU limit off...
