727 yoke wont come out. What's the trick ?

AJ/FormS, Must have been B). kinda popped loose on the press. Thanks for your input ! The crank is a 4.25" stroke Eagle forged 8 bolt unit. will be using a trans brake rear band apply VB. 3200-3400 stall converter. yes, I'm building it from the back to the front. have a 410 dana 60 and a 373 8 3/4". shortened both, tubbed. looking for 3.55's. S/B the best for the street. just the gears for shipping purposes. if i can get a whole diff. local i will. Lots of aftermarket parts for the trans. lowering 1st with planetary to match the cam with the 3.55. anyway, thanks
