When a 4R70W, 4R75W, or 4R70 automatic transmission starts slipping under load or shows signs of clutch pack heat damage, one of the first components to inspect is the steel separator plate. This listing is for a single hi-performance kolene-treated steel plate designed for these units, covering applications from 1996 forward.
Kolene processing gives the steel a harder, more heat-resistant surface than a standard plain steel plate. In transmissions that run hotter than stock, whether due to towing, performance driving, or a previous rebuild that left heat damage in the pack, a kolene steel helps the clutch pack maintain consistent clamping force over a longer service life. The surface finish also reduces the tendency to glaze, which is one of the common causes of soft or delayed engagement after a rebuild.
This is not a kit. There are no friction discs, no gaskets, no seals, no Automatic Transmission Filter, and no additional hardware in this shipment. It is one plate, part number, pulled and verified individually before it ships. If you are building a full clutch pack, you will need to source the remaining components separately.
Before placing your order, match your unit code exactly to 4R70W, 4R75W, or 4R70, and confirm the vehicle was built in 1996 or later. Also verify the steel count and thickness spec for the specific clutch pack position you are rebuilding, since different positions within these units can call for different plates. Ordering the wrong plate and having to return it costs time on both ends, so a few minutes of confirmation before purchasing is worth it.
Since 1991, REMCO has worked exclusively in automatic transmission parts. Each piece that leaves here is checked against its part record before it goes into the box.
- Restores holding capacity in 4R70W, 4R75W, and 4R70 automatic transmission units where worn or glazed steels are causing slip, heat buildup, or inconsistent clutch engagement.
- This listing covers one individual steel plate only. No friction discs, no seals, no gaskets, no Automatic Transmission Filter, and no rebuild kit are included. Confirm you need this specific piece before ordering.
- The kolene surface finish on this steel increases heat resistance and reduces glazing risk compared to plain steel plates, making it suited for performance or high-cycle applications in these units.
- One hi-performance kolene-treated steel plate, listed under the 4R70W 4R75W 4R70 application. Shipping weight is 3 lb. Part number for reference when cross-checking your parts list.
- Before ordering, verify your transmission code matches 4R70W, 4R75W, or 4R70, and confirm the build year is 1996 or later. Check your existing steel count and thickness to ensure this plate matches your unit's specification.
