Automatic transmission failure and electric coolant temperature sensor failure in 2006 Honda Civic ex. Noticed change in driving feel over past couple of weeks--shifting was jerky, not smooth; seemed to rev slightly higher at times while driving. Engine warning light came on 2-13-13 when starting engine. Also, green light next to "drive" on the dash started blinking. Took car into Honda dealership the next day. Was told that the transmission fluid was burnt, transmission had hydraulic issues, gears not shifting properly. New transmission installed. Had all previous regular maintenance performed at Honda dealership, on schedule.
Transmission is failing it is flaring. Rpm rises to 6-7k rpm and it still around 20-30 mph. And it slowing increasing speed. This is dangerous, when I am trying to merge in traffic I don't have the acceleration I merge on highway or just getting on a street.
