Morning guys! I have a x type 3.0 v6 auto 2001. Yesterday I had an hours long journey and on the return leg about 10mins till my home the powertrain malfunction light came up with no other lights. The car didn't change it's drive wasn't in limp mode everything was working changing up and down smoothly. I read the codes and there were none. I drove cautiously home and this morning started her up and the lights gone. Should I be worried? Is it worth getting the transmission fluid checked? Just went for a little drive and it's on point no issues at all. Is there a sensor I'm missing or ecu issue. Any help would be great I've looked online but all other posts seem to have a drive issue along with the light. Thanks
