I have a 02 intrepid and it works fine in reverse but when you put it in drive it will not shift from whatever gear its in whether its 2nd or 3rd. it doesnt matter if you pull it down in low or 3, it still wont differ, My scanner isnt tellin me too awful much about this code, and it has no other trans codes the other codes are p0441 and p0135. i was just wondering if this is the trans controller of if it is somthing mechanical in the trans, I'm kinda leaning toward something electrical, because it seems to only do this when the engine and trans has warmed up
