All of these codes lead to a C-3 pressure switch that is stuck on. C-3 pressure switch is located in the control valve module. It could also be a short in the wiring for C-3 pressure switch. C-3 pressure switch is a normally open switch. It is only supposed to be on when c-3 clutch is applied in 3rd, 5th, and reverse. Hope this helps. I agree with jetfuel4 get it repaired under warranty.
