Mercury Sable

I have a 92 sable with trany trouble. we replaced transmission in march. Ran fine for 4 months then water pump went out, when car got hot, tranny fluid went everywhere. Changed water pump, car runs great but still leaking tranny fluid. changed tranny pan gasket, and seal. Still leaking but can't figure out from where. It seems to be building up pressure and blowing it out only when hot, after driving 3 hours or so. Any idea's what this is and how to fix it. It took me 4 months to find this tranny. and had to have it shipped from PA to IL to get it. HELP

Our car that had similar problems was not a Mercury Sable, but we found out after it was too late that our car transmission filter was clogged and it kept throwing the transmission fluid out the dipstick until one day we burnt up the transmission.
I don't know it this helps, but good luck.
