Cat D3B Has Trans/hyd filter but is there any other suction screen?

I would like to know if the D3B has a suction screen to be cleaned for the transmission besides changing the filter. If so where is it? I don't have a book on this dozer. Thanks

    There should be a screen beside the drain plug on the bottom of the trans. square plate,4 bolts.

    Drained the oil and took the screen out, it's clean but the oil is dirty. What type of oil do I use for the D3B trans? Might as well change it.

    Did a forum search and found TO-4 SAE30 to be the trans oil required.
