there is no dipsticks on Galaxy's . you have to get the vehicle hot , on level ground ( ramp would be best ) with the engine running & in N or P get under the car and undo what looks like the drain plug, this is the level & you should get a small amount of oil run out, if you don't the tube for topping up is at the front of the gearbox with a cap on it ( cap can be a bit fiddley ) put oil in with engine still running untill it runs out the level hole on the sump.
