Clutch change in Hyundai Sonata 2001 Gasolin

How, it turns out that I am stagnant ... I have changed the clutch of a 2001 Hyundai Sonata and I am not able to separate the gearbox from the block. It costs me a triumph to separate it a little and if I leave it vueleve to recover its position ... Is it necessary I have thought that it would be able to separate the gearbox because I have space when it picks up part of the frame where the taco-motor, the trapezides, direction zipper are screwed ... I appreciate your help, thank you very much
