I don't think it's that exact issue as mine is only giving issues at low speed... but it has me wondering if it is that output shaft sensor that is going out - thank you
It doesn't exactly to me either but that lead frame does have both the sensor(s) and the slider switch thing for the transmission shift selector built into it, and a relatively easy/semi-cheap possible cure if not preventative maintenance, especially while doing transmission service. I was gonna say, a '13 with only 15k miles DAMN. My '13 has 162k and I haven't had any issues there yet but get will get replaced next time I drop the tranny pan. Good luck.
