About every 2 weeks in the morning when my wife is taking the kids to school she starts the car and when she shifts the car into Reverse she says that she can "almost immediately feel extreme hesitation starting down the driveway" The main drive of out neighborhood has a speed limit of 25 so when you get out there you have to speed up quickly. When she tries to do so she says "It just doesn't shift at all, It just drones on getting louder and louder as you try to speed up" "It feels like the car has no power, no pep, and certainly not the get up and go feeling I normally get" she has been able to get the car to the school zone (about 1-2 miles from home) before she has to pull over restart the car. After that restart it drives just fine and you wouldn't have even known what happened. Some people I've talked to think its computer related but knowing the history of the Outlook and Acadia transmissions I think otherwise. I have also noticed that when I'm merging onto the highway and I have to speed up to get up to speed the engine revs A LOT and REALLY loud. I'm talking 6,000-7,000 RPMs (I once got into the low 8,000 before the DIC said "Engine power reduced") the car actually begins to vibrate before it lurches forewords and then backwards rapidly accelerating. I can only describe it as the engine revving up really high and then free wheeling (it feels almost like the engine has disconnected its self from the car). This has only happened about 3 or 4 times but one time the Check Engine Light flashed along with a chime that Said "Service... " I didn't get a chance to see what else it said because it appeared and disappeared so quickly. The car also seems much less hesitant to downshift than before and sometimes downshifts and then shifts back up and back down again. Odometer is at 104,990. :help:
