2nd issue this morning with the 10R80 in a week. Pulling out into traffic in a right hand turn when it decided it wasn't going to go anywhere. RPM's climbed and then it let go scared the crap out of me with all the traffic. Called the Ford service manager and she is now going to look into it but...
I've had my DH for just about a year now and just the other day I pulled up to a stop sign and when I pulled away the RPM's went through the roof car jerked and engaged the gear. 1st time it did that but scared the crap out of me.
That's exactly what I thought. I had already taken it to Ford but they were unable to find the noise and I originally thought is was a suspension issue. Turns out it was the RS passenger rear seat.
