It was well dark by the time we got the tranny off, but the seal looked ok. I initially thought it to be coming out of the bolt holes like D said.
I ordered new hardware from UUC before install -- all new proper length bolts with the torque plate.
I'm just nervous now with those holes threaded, the missing screw, the damage and the fact that it came off once...
Before shot -- no missing screw, no damage
