Also, if you're installing a cannister filter it's always good practice, like with an engine oil filter, to add fluid to the inside of the filter so it's not running completely dry when you fire it up for the first time after the fluid swap.Īuto transmission pans can sometimes be a bugger to seal properly, and most synthetic transmission fluids like the ATF+4 required by most Jeep autos is quite expensive. When installing your new filters, lube any O-rings, bushings, or gaskets with some ATF to help prevent nicking and galling as it's inserted. No matter what the case, after you remove the old filters, clean the mounting surfaces with a little aerosol cleaner and inspect for grooves or damage. Also, some auto transmissions may utilize two internal filters, one being the flat filter and another a cannister filter that resembles a small, short engine oil filter. Most of these, as is the case with this AW4, are bolted to the transmission valve body, although some insert with a loose press fit into a plastic bushing or with a rubber O-ring, or some combination of all.
