If this started just after a trans removal/installation, check around the trans bell housing to see if they pinched some wires or unhooked somthing and didn't get it back together. I'm thinking that the harness for both banks originates on the pass side of the engine and then bank 2 runs down the pass side of the bell housing where it hits small protective enclosures where the O2 sensors plugs are and, I'm thinking they are attached the the stud/bolts that hold then trans to the engine. Same for bank I except on the driver's side.
