904 help

Well guys and girls Ive been checking this most wonderful site for some time now and 99.9% of the time I find the answer I need. But this time I need all the help I can get. I have had the trans out of my 65 barracuda 3 times in the last 2 years for the same problem. It starts pouring fluid out the front under the torque converter. The motor trans rebuild has at most 10,000 miles on it. The car has been completelly restored for about 12 years. The last time I had it out had the converter hub and input shaft checked. ID" OD" is good. All new seals and bushings throughout. Motor is 273 commando .030 over MP purlple cam. .450 .455 spitfire headers. and of course the problem child of mine 904A cable shifted trans. If the car wasnt all original the trans would be in the trash by now.
