Getting bushing and washer dimensions right inside a 4F20E or RE4F04A/RE4F04B unit is the kind of detail that determines whether a rebuilt automatic transmission holds up through normal service or comes back with noise and shaft wear in a short time. This set is sized specifically for those three unit codes and covers the 1992-and-up production range, so it is not a generic lot pulled from bulk stock.At REMCO, in business in automatic transmission parts since 1991, each order like this one is assembled by hand. The components are checked against the piece list before the box is sealed, and that same list ships inside so the installer can count and confirm everything before the unit goes on the bench. There is no prepackaged inventory sitting on a shelf waiting to be grabbed: the set is put together for the order.What this listing covers is the bushing and washer set for the RE4F04A, RE4F04B, and 4F20E. It does not include friction discs, steel plates, sealing rings, a filter, or a band. If your rebuild requires those items, they are separate purchases. Check your parts list against this content before ordering.Packaged weight is 1 lb. Confirm the code stamped on your unit is RE4F04A, RE4F04B, or 4F20E and that the vehicle build year is 1992 or later before placing the order. Ordering against the wrong code is the most common reason a return is needed, and a quick check of the unit tag prevents that entirely. Correct bushing and washer fitment for RE4F04A, RE4F04B, and 4F20E units keeps shaft tolerances within spec and reduces premature wear at critical rotating points. This listing does NOT include friction discs, steel plates, sealing rings, filter, or band. Review your rebuild needs before ordering to confirm this is the right part for your job. Bushings and washers control end-play and radial movement inside the unit. Using the wrong size or a worn piece at these locations causes noise, slippage, and accelerated internal damage. Content: bushing and washer set sized for RE4F04A, RE4F04B, and 4F20E applications. Packaged weight is 1 lb. A piece list is included in the box so you can verify contents on arrival. Before ordering, confirm the transmission code on the unit itself matches RE4F04A, RE4F04B, or 4F20E and verify the build year falls within the 1992-and-up application range.
