BLKA4000SQ

I have a 1984 4000 S Quattro. I have/am replacing major parts in a rebuild. Have replaced all the rotors, calipers, brake master, clutch master, and fluid lines. I need to replace the clutch slave cylinder to complete. The roll pin has been removed but the cylinder will not move from the bell housing. What method could be used to force it out that will not damage the transmission case? It should come out without having to remove the trans from the car.

i had to remove the tranny and air hammer it out
