When a pan service on an A604 automatic transmission calls for a fresh filter and a new bottom pan gasket, this two-piece set covers both in a single order without padding the count with parts the job does not need. What sets it apart is the straightforward match between what the box says and what comes out of it: one cork bottom pan gasket and one internal filter, nothing more and nothing less, because REMCO picks and verifies each order against the parts list before it ships.The cork pan gasket seals the bottom pan to the case and the filter sits in the valve body circuit where it catches debris before it reaches critical passages. Both pieces are selected for the A604 platform covering applications from 1989 forward. Neither disc clutches, steel reaction plates, bands, overhaul gaskets, nor any other seals are part of this set, so if your service requires those components they will need to be sourced separately. Checking your job sheet against this contents list before ordering saves a second delivery.REMCO has been working in automatic transmission parts since 1991, assembling kits by hand rather than pulling prepackaged boxes off a shelf. The included parts list in the box lets the technician verify the count on the bench before the pan comes off.To confirm fit, locate the transmission identification code directly on the unit and verify it reads A604, 40TE, or 41TE. Also confirm the model year sits within the 1989-and-up range this set covers. Weight is 1 lb. Restoring proper fluid flow and sealing the pan stops leaks that lead to pressure loss and shift problems in A604 40TE 41TE units. This set does NOT include friction discs, steel plates, bands, seals, or overhaul gaskets. Review your parts list before ordering to avoid a second purchase. Two components that wear together are covered here in one order: the cork bottom pan gasket and the internal filter, both matched to the A604 application. Box contains exactly 2 pieces: 1 cork bottom pan gasket and 1 automatic transmission filter for A604 [89-UP] units. Total weight: 1 lb. Before ordering, confirm the transmission code on the unit itself matches A604, 40TE, or 41TE and that your application falls within the [89-UP] range.
