One time I did see this code produced when the manual Park release was pulled then try and shift, but it also gets TCM codes for Park solenoid and other things, if this is your only code it's the ESM. This should be a warrant-able item as other mods including a tune should not affect this, remember for them to deny warranty they have to prove your mods affected it and caused the failure, as an example if you put a CAI and smaller pulley on it then the radio takes a shit, they have to warranty the radio because there is no possible way the mods affected it.
