I have a 2019 Ram 1500 5.7 Etorque. It is procharged and recently had it cammed along with some longtube headers. Had pcm and tcm tuned. Truck is running good but intermittently when I let off the gas and the truck starts to downshift it will make a noise and the check engine light will come on and I get a message saying check transmission press brake and put in park. DTC- P1DCD TCM monitoring processor performance, multiple clutches locked up. I pull over and restart the truck and it drives fine again like nothing ever happened then randomly it happens again. Seems to do it more when it is raining. Does anyone have a clue what the issue could be? If it could be a problem with the tune or maybe a sensor? Its odd the transmission shifts perfectly fine a lot of the time then will randomly throw this code after letting off the throttle sometimes.
