It´s not exactly a "filter", but a little, round, thin metallic screen, with a strong rounded magnet on the inner side, preventing bigger dirt getting along the rest of the tubing/hosing.
There are other actually filter in this system, but I have not dealt with them this time.
In this tractor, the system is the very same for BOTH the transmission AND the hydraulics on the back.
Down here in Brazil, providing all the climate differences, I use a 10W30 oil/fluid for this case.
It´s most likely it would not be necessary to add the rubber/silicon around the "filter" cap, but it will do no harm and works as an extra anti-leak measure.
