I have a 2005 with the 42rle and have the p0740 code, I have replaced all of the solenoids and have checked all of the wiring and looks good, I have changed the oil in it multiple times with the filter it only comes on when driving on the highway for about 20 mins after resetting the code, when the light comes on nothing happens no shudder and shifts good, I think it could be my PCM?
