2006 Chevrolet Impala Powertrain (other) Problems

First battery needed replaced every year then few weeks ago with no warning light or messages that battery was dieing the battery died again it was replaced then it started reving up and down on its own while driving so it goes faster then slower on its own when it feels like it.. TPS wont show tire pressure cant relearn tire positions now dash lights works usually then don't bright lights don't work now if automatic light control is on car shakes bad while breaking idles hard uses ALOT of gas now massive amount of heat coming off engine now with no dash light or guage saying temp is going up engine smells kind of bad after driving the car replaced transmission once couple years ago transmission maybe going out again the gear shift locks don't work it slips out of gear and into another gear effortlessly while driving and while parked without pressing the button to move the gear shift clicking or tapping noise started coming from front end only when turning left now does it while.turning and sometimes while.going straight and it's all still happening... theres more but not going into all of it now. DTC code listed 2days ago was listed as: B1000-00 Electronic Control Unit. Searched Google for code and got posts saying ECU needs replaced..updated or reprogrammed and some say BCU needs replaced..upgraded or reprogrammed. Each time I search the code I get a different reason for the code and different meaning. I have a 2006 Chevy Impala SS 5.3L V8 with police package. Car is available for inspection anytime.

While I was driving I had to stop on a hill and when I pushed the gas to accelerate it wouldn’t move the engine just revved up and hasn’t moved since just when you push on the gas and the rpm’s go up to 5-6 and it will move maybe a foot or so. There was no warning or messages that appeared before this happened and even now after it’s happens and it’s not showing any code to what’s wrong with it. It affected my safety and others because it wouldn’t move while in the middle of the road and I could have got in to a serious car accident because of it.

IN MY 006 IMPALA SS THE TRANSMISSION IS STARTING TO SLIP. THE CAR IS AROUND 83,000 MILES WHEN I FIRST NOTICED THIS ISSUE, AND THE VEHICLE WASN'T DOING ANY HARD ACCELERATION (AROUND 20-25 MILES AN HOUR SHIFTING FROM FIRST TO SECOND GEAR). I AM WORRIED THAT I WILL HAVE TO PAY TO GET IT REPLACED.
