As long as we are speculating, I would be concerned that they forgot to
put a pilot bearing into the rebuilt motor. That lets the pilot/input
shaft wobble against the tranny seal and then the seal leaks as well as
you can get damage to the oil slinger sleeve.

The tranny seal can leak without much oil getting into the clutch disc.
The release bearing operating sleeve is designed to catch leaking tranny
oil and let it drain straight down from a hole in the bottom of that sleeve.
