96 caravan transmission trouble Help me Please

Hello, i have a leak in my transmission coming from between the transmission and the engine, I tooked it to the transmission shop and they changed all the seals an the torque converter but the problem continues now it happened only after the van is warmed out, They told me that the tranny is crack.
Could you help me to figure out if this is possible or you think there are another place where it can be leaking Thank you.

I am still betting on the torque convertor seal but I have also seen the front pump gasket leak. You will have to look to tell.

thank you taillight for your answer, I have two more questions, is the front pump the big o'ring about 12 inches? and do you know any additive that can I use to stop this leaking? Thanks againrunaround

Yes that is the front pump. The only brand that has ever worked for me was KW. It even comes with a money back guarante.
