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

Also, the pro trans. Have 2 bearings. The stock one and add one in the carrier. The one ton has the second one in the back, instead of the bushing. From towing heavy *** loads uphill, the carrier, aluminum, got hot, expanded and galled and got stuck to the shaft. That's why I rebuilt the trans. Used the carrier from the parts trans. Stuck the shaft on the lathe and removed the aluminum. Figured I'd do the Cuda trans and get it out of the way. Seeing as I found a problem, just looking to not repeat it...
