Just to add, the oil in an automatic _is_ pressurized, which means it can
be forced where it needs to be.

If that's the case, it would probably explain the difference Ivan was
referring to. I've never taken an automatic transmission apart myself.

Best wishes,

Many constant mesh standard transmissions run automatic trans fluid,
engine oil, or specifically synthetic engine oil.
Some constant mesh transmissions also run GL oil.
Most sliding gear standard transmissions (Non constant mesh,
syncromesh) use GL rated (heavier) oils.
Virtually all Hypoid differentials use a GL rated heavy gear oil.
Worm gear drives use a specific worm gear lubricant - extremely heavy
"lard like" lubricant
