When a 4F20E automatic transmission shows clutch pack slippage or uneven engagement, a worn or scored steel module is often the root cause, and replacing it with a correctly spec'd piece is the direct fix. This listing is for one steel module matched to the 4F20E, also catalogued under the RE4F04A and RE4F04B references, covering 1992 and up applications.The part ships as a single steel module at 2 lb. There are no friction discs, no seals, no gaskets, no filter, and no band in this order. If your rebuild requires those components, they need to be sourced separately. Knowing exactly what is and is not in the box before you buy keeps the job on schedule.At REMCO, components like this are pulled and handled individually, not dispensed from a bulk prepack. That means the piece you receive has been confirmed against the part number before it leaves. REMCO has been working in automatic transmission parts since 1991, and that single-unit care applies whether the order is one steel module or a full rebuild kit.To confirm fitment, check that your unit carries the 4F20E code or is cross-referenced as RE4F04A or RE4F04B, and that the application year is 1992 or later. If there is any doubt about the unit code, verify against the transmission housing ID before ordering. Returning a part because of a unit mismatch delays the repair unnecessarily, and this part has a narrow application, so fitment confirmation is the most important step before purchasing. This steel module addresses worn or damaged steel contact surfaces in 4F20E units, helping restore proper clutch pack engagement and prevent slippage caused by worn steels. This listing covers the steel module only. No friction discs, seals, gaskets, filter, or band are included. Review your full parts list before placing your order to avoid a return.
