Working through some kinks on a new-to-me Z06. There are signs of a small leak from the weep hole at the transmission/torque tube. evidence of oil on the bottom of the transmission caked turned dark with dust, heard its called butt rot on a transaxle car. the car shifts perfectly, hasn't leaked any fluid on the floor....unless I jack up the rear. Then I will get a slow drip from the weep hole by the torque tube. I changed the exhaust recently and when the rear was jacked way up it dripped quite a bit. I figured I'd at least top it off for now while I figured out what was up. I leveled the car out on jack stands and opened the fil plug and transmission fluid poured out of it. Maybe 3 or 4 oz. Surprised me as I figured it would be low. I let it slow to a drip then put the plug back in. I ran the car for a bit to circulate the fluid, maybe 30 seconds. The prior owner had the torque tube rebuilt about 2000 miles ago. its a 2006 Z06, was told it has a TR6060 swap.
What could be going on here?
I plan on driving the car a bit and checking the fluid again. Only way to check the fluid is to take the fill plug off and top off correct? How can I check if its the TR6060 in this car?
Thanks all?

If the fluid flowed out of the fill plug with the vehicle level, then somehow the trans was overfilled. Clean everything & keep watch to see if there's still any leak.
