Getting the right filter matched to the correct model and year is the first step toward a transmission that holds pressure and shifts cleanly, and that is exactly what this listing addresses. This is a single replacement filter selected for C4 and C5 automatic transmission units built between 1965 and 1969, carrying part number CFI-005544 and weighing 1 lb.The filter sits at the inlet of the pump and is the first line of defense against particulate circulating through the valve body and clutch apply circuits. When this part is restricted or degraded, fluid volume drops, line pressure becomes inconsistent, and internal components wear faster than they should. Replacing it as part of any service or rebuild on these units is not optional if the goal is a transmission that lasts.This listing contains one filter and nothing else. There is no pan gasket, no o-ring for the filter neck, and no hardware included here. If your job calls for those components, source them separately before you begin. Checking your complete parts list against what you have on hand before disassembly saves time and prevents the unit from sitting open while you wait on additional parts.REMCO has been working in automatic transmission parts since 1991. Each order assembled here is checked against its own part record before it ships, so what arrives matches what was ordered. A part list is included in the packaging.To make sure this filter fits, confirm two things: that your unit is a C4 or C5 and that the vehicle it came out of falls within the 1965-to-1969 production window. If either of those details is outside this range, a different filter number applies. A clogged or degraded filter starves the valve body and clutch packs of clean fluid, leading to slip, delayed engagement, and premature wear inside the unit. This listing covers the filter only. No gasket, no sealing ring, no pan hardware. Check what your rebuild requires and order those separately before you start the job. Sourced specifically for C4 and C5 applications from the 1965-1969 production range, so the inlet neck, mounting tab, and screen dimensions correspond to the original design of those units. One filter, weighing 1 lb. The part number on file is CFI-005544. That is the complete contents of this listing, nothing more. Before ordering, confirm your transmission code is C4 or C5 and that your unit falls within the 1965-1969 application range. A wrong model or year will result in a filter that does not fit.
