4 Wheel Drive/SUVs: 700R leak, chevy 4x4, fly wheel

Question
i have taken out my transmission 5 times and replaced the fly wheel, torque converter, pan gasket and filter,, and put in 2 new front seals.. The problem is i STILL have a major leak from the area of the torque converter and it has me stumped. I havew heard a few opinions that it could be some sort of bushing that is on the front shaft,, is this correct or am i missing something else ??  The fly wheel was warped and the torque converter had a crack in the neck that is why they were changed,, the vehicle is a 93 ext cab chevy 4x4 with a 90 model 700R transmission. ANY help on this would be a great help

Answer
Don, it is really hard to say what is wrong , but I would say its something in the front of the trans like a front bearing isnt in strait , or something to that affect , since you have tried so many times , good luck, why dont you take it to a trans shop and ask them to look at it for you . ADAM
