that sounds pretty straight forward. i'd follow these step when changing the g/b fluid. But what i need help with though is removing the oil filter. When i last changed it, i think i placed one which does not allow me to have enough leverage to twist the filter off and ive tried all tyres of oil filter wrenches with no success. Ive seen another type, non clamping and twisitng anti-closewise model, where you just place it over the filter and tighten a screw then twist. The only one with this is that the handle you use to twist seems to be too long to have enough clearance to undo the filter. any suggestions.
