Ford 555 Torque Converter Oil Leak

I was doing some heavy pushing with my 555
backfilling a ditch. Noticed an oil leak and
found out it was coming from a plate on the
bottom of the torque coverter. All still works
fine but wont when the oil runs out. Does anyone
know what the likely source of the leak is? It
is definitely torque conv. oil, nothing on dipstick.
Thanks for any help
 
There are a couple of things there that will leak in there..One is the oil pressure tube and plug visible from bottom cover , Next is the Blocker Valve that sits on top of the front cover assembly..This Blocker Valve contains the shift spool and base gasket..The last is the front pump that powers the reverser unit..Pump there is powered by the torque converter...
 
I had a 5500 hoe. Had oil leak in bottom housing. I pulled the engine and rebuilt the trany. looked good - back together - cranked it up - still leaked only worse! Pulled it down again - back to ford for another gasket kit - back together still no change. This time I got a black light and dye. Had to start and remove starter with it running - injected dye - The torque converter housing was leaking - back down again! By now this is getting old! Took the converter apart looked good. Checked the o ring - it looked good as well. Got another gasket from Ford,installed the new o ring. Now the problem! I noticed I had to stretch the new o ring to place it in the grove. I mic'ed the o ring in place and it didn't reach the top of the housing. Went to the bearing house and got the right o ring. Still running after 10 years. Don't trust Ford to give you the proper parts.
 
don't know if your tractor is the same, but we had a 555 backhoe and had trouble with power being down,..turned out it was converter,..had a 2 stage converter and was stuck in high side,..nothing to do with your leak but something to keep in mind,....
