have a trans guy look at it and scan for codes, control relay may be your problem. also check fuel pressure

already check the fuel pressure, new fuel filter also, trans does not slip it makes the gear changes very smooth and good and the code came like 1 month later, i puled out the code my self with my scan tool , in neutral engine stumbles when on high RPM already went to the mechanic and they could not find nothing wrong with the engine ... but also my ecu has no communication with live data, mechanics blame the computer (ECU).
