Yeah, I just did the same thing about 5 minutes ago, did a U turn, thought I was still in manumatic, and then i shifted up, watched my RPM shoot up past 5, and then shifted back into drive. Scared the [censored] out of me, but its still running and fine. I guess it's not good for the tranny if you repetitively do so, but once should be ok. It was only for a split second.
