On most transmissions that are certified for 30 running with no oil in the sump or loss of the pump(s) most of the individual gears in the transmission have hollow shafts which are filled with some absorbent material. When the transmission starts turning some oil is absorbed by this material and stays there while the transmission is turning. When the transmission stops most of this absorbed oil will drain back into the sump. Each gear that has this material installed has small holes that allow for centrifugal slinging of this retained oil into the respective gear meshes.
The EH 101 not only has this facility it has two separate oil sumps each with it’s own pump to cater to the loss of a pump or battle damage to one of the sumps. If both sumps are compromised the transmission can be run for 30 minutes.
If this has already been addressed please forgive me.
