TSB 19-2090: Surge Or Hesitation With No DTCs

[Cobra Jet]

Just FYI for the GT350/350R owners, see attached TSB.

This TSB supersedes 18-2322, applies to all 2015-2019 (quote is directly from TSB, grammatical typos and all)

This article supersedes TSB 18-2322 to update the Tool List and vehicle model years affected.Issue: Some 2015-2019 Mustang GT350/GT350R vehicles may exhibit a hesitation or surge inthe vehicle with no diagnostic trouble codes (DTCs) present. This may be accompanied by aninoperative cruise control system. This may be due to a transmission output shaft flange nut thathas become loose, allowing the output shaft tone ring to move in relation to the output shaftcausing an erroneous signal. To resolve the condition, replace the output shaft flange.

Just ran my car on freeway with cruise control on. Works perfectly and didn't feel the hesitation that i have felt before. Still need to check the code for engine light and figure out why my A/C isn't working. Anyone have any issues with OB2 readers that don't work on our cars?
