Oil change along with filter air filter pollen filter very straight forward, engine coolant same, diff oil easy job, atf in 6speed auto very easy to drain pan and fill, however no idea how to get all atf out the torque converter. So just drain 3 liters at time,Plugs are bit more difficult need to remove quite a lot to get access to them, more time consumpion then difficult. Car is Lexus gs 250 f sport.
