I was driving down interstate 19, when the transmission started to fail, there was heavy traffic and my car going up and down on speed limit, 65-35 miles per hour. Almost had cars behind me rear end my Acura Cl, so I pulled over to avoid a sudden accident, the vehicle had just been in the Acura dealership for a minor inspection of a sudden noise in the transmission area. They advised me that it was starting to miss and did not mention not to drive it. A new traansmission costs $4700.
