The oil cosumption most likely the valve guides. Small amounts of oil get by vlave guides due to seals getting old a cracking. If you can live with it it really won't get to using any more oil.
The plug usually detonation crackes the porceline but you don't speak of any. If the cylinder runs lean combustion temps rise and may blister the plug and piece could chip off. If the plug is really white and has black spots on the porceline then it is high cobustion temp. Injector maybe dirty or not spraying full shot. Try cleaning injectors.
As for tranny flush is good and yes have filter replaced.
Let me know this plug thing intrigues me
