What about the filter(s)? I can't seem to find anything on that.

Hi John,
to give you definitive answers, both we and Caterpillar require a Serial Number to give you both correct information and Parts.
Cat continually made changes thru-out production of machines and so a machine one serial number before or after yours could have old or new type trans. filters, lines, engine, etc.
Cat and we do not use the year your machine may have been produced for the same reasons.
Cheers,
Eddie B.
