SSM 50555 - 2020-2021 Mustang GT500 - Various Drivability Concerns With Powertrain Malfunction (Wrench) Indicator And DTCs P1601/P061A

Some 2020-2021 Mustang GT500 vehicles may experience erratic and harsh shiftingat highway speeds and/or reduced speed when accelerating from a stop, with a powertrain malfunction (wrench) indicator and DTCs P1601/P061A while using SelectShift™. This may be due to powertrain control module (PCM) calibration. This condition does not affect vehicle durability and no additional diagnosis or service is required at this time. Inform customers that they can continue to drive the vehicle but not to use SelectShift™. Engineering is currently working on a solution for this condition that is expected in April 2022. Replacement or reprogramming of the PCM will not resolve this condition at this time. Schedule a follow-upappointment for repair in April 2022. Once the update becomes available, contact the customer and confirm the service appointment. Monitor OASIS for updates.

Sigh...

Do you have the potential affected VIN’s?

"Some" 2020/2021's. That's it.

WOW.

I’ve had wrench and only every other gear on shifts. I was able to clear by unclamping and re-clamping harness connectors.

This sounds a bit more problematic????

Just dropping in the actual TSB 22-2280. This doc was released in July 2022 for the DTCs P1601/P061A in the event someone needs the TSB doc.
