P0884 Dodge - & P0522 how are these related?

Question

I have these 2 codes. P0522 & P0884. The car throws itself into neutral, at the same time the oil light comes on, then about a minute the car jerks back into gear. It does it after the cars at operating temp. It does it going about 20mph. I've had the oil pressure sensor replaced and the PCM re-flashed and that fixed the problem for 8 months. Now it's doing it again. I had the oil pressure sensor replaced again but it's still doing the same thing with the same codes. It's been to the dealership both times. the 2nd time for 9 days and it does it while their driving it and they don't know what it is. Something is telling the oil pressure sensor theirs no oil. It says theirs low voltage and an intermittent signal. It's got to be electrical. It's not the TCM. That's shifting funny because it thinks theirs no oil when there is. But what's making the oil pressure sensor say theirs no oil???? These cars are notorious for bad grounds. I need to fix it and sell it to the next sucker but no one can tell me what it is. Help me get rid of this death trap on wheels.
Please if you know someone who's fixed this let me know I'm desperate.
