1995 Mitsubishi Galant CV Joint

The transmission went out in my car...I bought another used transmission but my problem is the CV joint wont come out...Ive tried everything that has been suggested to me...I used a come a long and it broke so I went and bought a 4 ton and it still wont come out even with a lot of pressure applied...It was also suggeted that I use a large pry bar along with the pressure and still nothing...If anyone can give me some advise that might work I would sure apperciate it...
