Hey my wife has an 08 Limited, and it is doing the same thing yours is from the sounds of it. Did you replace those sensors yet? Did it fix the problem? We discovered if you just clear the code the problem goes away. Well, let me explain, you can be truckin down the road and the odometer will read 'odo data error', the transmission will kick out of overdrive, the wrench light, the airbag light, and eventually the tire pressure monitoring system shows faulty as well. If you slow to a stop, it seems the transmission slips a lot until you get up to a certain speed (20-30 I think) and it will start shifting again but only up to drive. Also if you park it and put it back in any gear it slams hard. Like make you cringe kind of hard. But, like I said you clear the code, it's normal again, for 20 miles to 3 days. You can't predict it. So being that said I've come to the conclusion to just replace the sensors. Let me know what you came up with.
