When the filter in an A604 automatic transmission is restricted or damaged, fluid cannot circulate at the pressure the hydraulic circuit demands, and shift quality suffers before a nything else fails. This listing covers one replacement filter designed for A604, 40TE, and 41TE units built from 1989 onward, sold as a single piece at 1 lb.This is not a kit. There is no gasket, no pan gasket, no seals, and no solenoid included. Technicians who need a complete overhaul or service kit should look at the corresponding kit listings before placing this order, because this item will not cover those additional components.The A604 filter mounts inside the pan and is responsible for keeping debris out of the pump inlet and valve body passages. A collapsed or plugged element restricts flow enough to trigger soft shifts, delayed engagement, or pressure codes even when all other components are still serviceable. Swapping the filter is often the first step in any fluid service on this unit, and using the correct filter for the application keeps the hydraulic system working as designed.At REMCO, individual components like this one are picked and verified against the item record before shipping, the same process applied to every multi-piece kit built in house since 1991. The item shipped matches what is listed here: one filter, nothing more.Confirm the transmission identification code on the unit is A604, 40TE, or 41TE and that the vehicle year is 1989 or later before ordering. If there is any doubt about the application, cross the part against the unit ID tag rather than the vehicle model alone, since this transmission was used across several platforms over a long production run. Replacing this filter restores proper fluid flow through the valve body, preventing pressure loss and shift complaints caused by a clogged or collapsed element. This listing is for the filter only. It does not include a gasket, pan gasket, seals, solenoids, or any other component. Check what your job requires before ordering. The A604 filter sits in a specific position inside the pan and is the first line of defense against debris reaching the pump and valve body. Using the correct replacement keeps that protection intact. Content: 1 filter unit. Weight: 1 lb. No additional pieces are packed with this item. Before ordering, confirm the transmission code stamped on your unit matches A604, 40TE, or 41TE and verify the model year falls within the 1989-and-up application range. Show more
