Driving on interstate 75 at 70 mph the automatic transmission suddenly downshifted from overdrive into 3rd gear. The sudden surge almost sent me into the median. This has happened 5 times in the last month. The dealer has replaced the speed sensor unit twice and problem continues. Dealer kept old parts.
