Cayenne Turbo Trans issue
70k miles on my 2012 Cayenne Turbo. Suddenly Trans refuses to shift out of 1st in Auto Mode. Manual Mode works perfect.
I'm also able to move on manual in any gear to auto while driving and than still no auto shift - until I slow to maybe 5 miles - than trans moves to 1st.
But trans will not move out of 1st on its own!
Open to ideas of what is causing this.
