Transmission pan leak 727!!!!!!!!!!!!!!!!!!!!

Any body got any super ways to stop the pan leaking on 727,s i have had a lot of mopars in the last 35 years changed lots of everything on these cars i love it but was never to concour the pan leak on 727,s seems like it starts to leak when cooling off to cold , doesn.t seem to leak when hot , coming from pan only. right now i have one of the new pan gaskets off the dodge truck supposed to be reusable and the answer for this leak , but no way seems to be worse than the cork or rubber gasket , tried different pans ect over the years that doesn,t work either , would the 1 3/4 deeper pan work , anybody using these cheap chrome pans , wondering if they work , thanks alot.
