I have had my 14 auto non Z51 since August 9th. and have had no problems. Twice however at highway speed and trying to find the fast lane, including today on I95, I experienced high rpm's but no increase in speed. Kinda took me by surprise, and it was a little scary,and had me worried something was wrong. In that heavy traffic, my only thought was to maintain control. Now sitting here thinking about a reason for the high revs, I wonder if I accidently hit one of paddles. Has this happened to anyone else?
