Upper leak in M5OD-R1 HD

[gw33gp]

I have a small leak in upper area in the transmission in my 02 Ranger 4.0 with a stick. I thought the leaks at the plugs on the top were resolve by 02. Is there anything else up there that could be leaking?

I am keeping a eye on the fluid level and it is good so far.

Other than the plugs, there's only two other places I can think of. The shifter cap thingy and the top plate of the trans (it has a gasket).

Ok, I after my next race, I may decide to drop the transmission and take a look. The transmission has 175K miles on it and still works very well. Is there anything in it I should consider replacing in it while I have it out?

The clutch was done 75K miles ago and should need no work. I might consider replacing the slave cylinder if it shows any indication of weeping fluid.

While it's out, I'd replace the front and rear seals. And putting in some metal plugs wouldn't be a bad idea either.

I recently put a M50D in my Ranger and before I put it in I:

power washed it (it was a pig)
changed all the seals
replaced the rubber plugs with metal ones
and did a shifter rebuild

Works like a champ and doesn't leak or seep!
