Hey guys. Dont know much about auto trannys just got a 350 and 700R4 combo, Anyways the motor and tranny were both rebuilt about 11k miles ago. But I recently noticed after driving for a while, when I park it I get some leakage from the hole in the bottom of the transmission (bellhousing?) I checked the dipstick and its not burnt discolored or anything, BUT it is overfilled. Its actually to the words pointing to the "full if here" markings. Is it just bleeding off fluid? Should I be concerned?

 

Upper front seal could be leaking. If it is coming from the dust cover shield area that could be it.
