Tranny Leaking need help!

[88-5.0mustang]

So my standard tranny is leaking out of the yoke, so i went and picked up a seal for it, i got home and pulled the driveshaft and began to remove the seal. For some dumb reason something this simple it will not come out, is their any special tools needed, or maybe just a techneque to use, Ive never pulled one of these things so any help would be greatly appreciated.
thanks

A seal puller will get the seal out. If the yolk is not smooth then you need to replace the bushing in the tail of the tranny or it will still leak. And get a new yolk also.
