I recommend this strongly
That is why above i said to verify the fill level
meaning drop the pan and scribe the dipstick

3 second recovery time from 0 is bad.
should be fractions of a second

It likely goes between the Output Carrier and Reaction Carrier which are the first and second assemblies you dropped in the case (first, second, last pics above). There is also one between the overdrive assembly and the forward clutch assembly but looks like that one may installed in your second to last picture above.

Thankyou i found out where it came from for some reason it just fell off from inside the carrier btw my direct drum housing was so scored [ where the four seals go] that im pretty sure it would not seal much at all i had a spare direct drum casing with no damage hopefully thatll fix my low pressure issue i was having im not sure ... this is a pic of the spare one i had but the one i took out had four lines in it im assuming the piece that goes in it dug into the housing inner bore possibly causing a major leak can any one confirm that theory
