Help on 99 7.3 tranny leaking

So after dong lots of reading on this site I found out where (more like where not) Im leaking motor oil from. Long story short I'm not leaking from any of the hpop line but more likely the gasket or the pump itself, so I will probably just change the pump and the gasket to be safe.

Now onto my tranny issues.

So after degreasing the engine its no longer dripping down (still filling up in the valley at this point and its a slow leak) so now I've noticed that I am leaking tranny fluid. I probably didn't notice before because it was mixed in with the motor oil.

about the leak, its not a massive leak but I notice it around the plate that covers the flywheel or torque converter, after removing the cover I could feel a small puddle at the bottom of the bell of the front of the tranny. I ran the truck without the shield and didn't notice any oil leaking. I put the shield back on and took a drive and it stared to leak again.

Not pulling any load, easy driving. The fluid is full and pretty clean.

Any ideas?

Cliffs:

Tranny leaking fluid from the area around the TQ converter or on top of the tranny in that area though.

The t/c seal is probably leaking make sure you check the t/c hub and pump bushing for any wear or grooves

Is this the same seal everyone says leaks after they overheat the tranny?

Yes it will dump fluid when run to hot I've worked at a ford dealership for 17 years done a many of them if you think you overheated it and you are not experienced any slippage or shift problems I would drop the pan see if you have any excessive material there will be some in there so dont get to alarmed replce seal and check items previously told you about and add a cooler make sure the cooler is in front of ac condensor hope this helps

is it common for it to leak without over heating the tranny?
