P7020 and p0722 codes
Have 2001 Ex...119K miles... Trans 1 1/2 yrs old.. new COPs, harness, cables etc.. new spark plugs... just replaced 3 sensors (1 on diff rear, 2 output on top and back of tranny.. ). Turns on great, however as soon as I put it in reverse and have it idle, the O/D light starts flashing and engine sputtering like it wants to die. The codes were P7020 and P07022. Any ideas anyone?

If the alternator starts to go bad and put out an AC current instead of a DC current it can do this. You need an oscilloscope to see this.
You could also have a wiring issue between the two sensors and the PCM.
