On my 2003 Neon (base model) I had the codes appear as P0841 with two P0700 codes. I looked around and found very little information other than "Transmission Fluid Pressure Sensor Switch "A" circuit range/ performance" as the cause of the problem. Now I understand the the pressure sensor is part of the PCM. Is that right? If so, that is an easy fix, if it's not too expensive.
