If either end of the special tool is set over an area of the spring retainer which is unsupported by the return spring, the retainer may be damaged. Compress the spring until the snap ring can be removed.

Remove the snap ring (A). Then remove the special tools (B), spring retainer (C) and return spring. Wrap a shop rag around the clutch drum (A) and apply air pressure to the fluid passage to remove the piston (B). Place a finger tip on the other end while applying air pressure.
