You can clear codes under the hood if there are any stored. Pull the PCM ign and PCM Bat fuses. Turn ign to on position and after a few seconds you will hear chimes from inside the car. Turn ignition to the off position, re-install fuses and codes, if any, will be cleared. It is good to do this then in a few days scan for codes to see if there are any. If there are any codes they would be "current" and not "stored" codes. Good tip for identifying any current issues the PCM or BCM may be picking up on

To reset your PCM, disconnect both positive and negative battery terminals. Then touch them together, this will completely drain the system of power and reset fuel trims. Then your car will learn the fuel trims of the gas you use. There are no adaptive pressure table in this platform. The 4L, 6L and 8L series transmissions do, but not these 4T series of transmissions
