    When driving at lower speeds 25-30 mph, the trans would start lugging and a groan type noise is heard. I thought is was shifting into 4th or even fifth gear. If put in sport mode, it will not happen. Took the car in for a sunroof issue and was told there is a trans ecu udate and asked me if I experienced any shifting problems. YES! so it is at the dealer now and hopefully it is fixed.

    At 40 - 45 mph on level road, about 1000 rpm, the transmission does not down shift and lugs the engine causing a vibration noise. If manually downshift to 4th, the problem disappears.

    My 2006 Acura TL stopped shifting into 2nd gear. Once I've started driving, the vehicle does not move to the next gear and stays idle causing me to pull off the road. I have noticed if I turn off the engine and restart the vehicle, the gears will move properly. I have had the transmission flushed with no result. Now, the Acura dealer tells me that it is my transmission but I'm not so sure.
