Magnefine, motorcraft, spx, and wix have inline filters.
Permacool is more expensive up front but allows just about any 3/4" threaded filters. So, the filter could be a Supertech/Proline/Generic PH8a sized(or PH977 double size), or pH3600/PH3614..... depending on how much room you have, or equivalent threaded boutique filter like Amsoil, Mobil1, RoyalPurple, Extendedguard..... Also, with an oil filter, I do recommend some stick-on neo magnets or a filtermag type device.
In a non-abused transmission, 30k is reasonable or every 2 yrs. If transmission has any known issues or is worked, 15k or once a year.
