Its been very cold these last few days and the car has been acting strange. At first it wanted to stay in 2nd gear all the time but if you got up to speed shifted into n then back to d it would shift. Today it wouldn't then it just lost all power. In park you can rev it to 2-2500 rpms for an instant upon start up then it dogs down and will only hold 1500 rpms let off the gas and it dies. You can only go 8-9 mph on level ground I brought it to advance auto and they scanned these codes po304,301,700,300,720,500,715 can someone point me in the right direction?

At this point I would concentrate on the 700, 720 and 715 faults they are transmission related faults reported to the engine ECU enabling you to use an obd reader telling you that there is an issue with the transmission---the problem is that you will need someone with factory or equal software to scan the TCU and determine what specifically has caused the faults(is it electronic or mechanical).---Your OBD reader can't do that!!

However running the car at high rpm and shifting will simple cause more damage--see an MB transmission specialist quickly!!
