When the filter does not match the pan depth, fluid draw is compromised and pressure irregularities follow throughout the hydraulic circuit. This is the flat filter built for the shallow pan version of the C4 and C5 automatic transmission, covering units from 1970 through 1983, and it fits only that configuration.The flat design is not interchangeable with deep pan setups. If you are unsure which pan your unit has, measure the depth before ordering. A filter seated against the wrong pan will not seal at the pickup point, and the rebuild will face the same fluid control problems it started with.This listing contains one filter. There are no gaskets, no seals, no bands, no friction discs, and no steels in this package. If your job calls for those components, they need to be sourced separately. The item ships at 1 lb.At REMCO, each part is pulled and checked individually before it leaves the shop. The company has worked in automatic transmission parts since 1991, and individual components like this one go through the same verification process as full rebuild kits. A parts list accompanies the shipment so you can confirm what arrived matches what was ordered.To make sure this filter works for your job: confirm the transmission is a C4 or C5, verify the build year is between 1970 and 1983, and check that the pan on your unit is the shallow flat style. Those three points are what determine fit, and none of them should be assumed. A properly fitted filter keeps fluid flow consistent and helps prevent pressure loss caused by a clogged or mismatched filter in the valve body circuit. This listing is for the filter only. It does not include gaskets, seals, bands, clutch discs, steels, or any other rebuild components. Verify your complete parts list before ordering. This flat filter is designed for the shallow pan configuration. If your unit uses a deep pan, this filter will not seat correctly. Confirm your pan depth before purchasing. Contents: one flat transmission filter for shallow pan applications. Item weight is 1 lb. No additional pieces are included in this listing. Before ordering, confirm your transmission code is C4 or C5, verify the model year falls within 1970 to 1983, and check that your unit uses the shallow flat pan to ensure this filter matches your application.
