Boy now, that was a shock - going to work, running 80, radio blaring, then this loud buzzing noise and feeling. Look at the Tach, and holy s%*#t - its between 5000 and 6000!! Pulled over with no-go situation and lots of lights blinking on the dash, specifically the Traction Control. Its a perfectly dry straight stretch, traction control???
Put it in gear again, no-go, and the tach just jumps. Turned off the car, counted to 10, and refired (done this with my tractor and my F350). Oh, and now it will go into Drive.
I start out again, and it sounds and acts fine. Blinking lights all go away, but the Code light is set. Got to work and pulled a Scan. The only Code was a U0101; "Onboard Computer; No communication with transmission control module". That is what it acted like, but sheesh, can't the electronics in this thing hold their liquor at speed?

Has anyone else had this problem??
