Bushing Sonnax Case (Rear) 1 Piece (3 Groove Front 1 Groove Back) E4OD 4R100

Sonnax Rear Case Bushing for 4R100 E4OD 1995/UP This upgraded Sonnax rear case bushing is designed to replace worn or failing OE bushings in Ford E4OD and 4R100 transmissions built after 1995. It features a late-style design with three lubrication grooves facing forward and one groove to the rear. OE bushings are prone to premature failure due to poor lubrication, excessive journal clearance, or insufficient load support. The Sonnax one-piece replacement bushing (part numbers 36008B or 36008D) offers superior performance compared to the factory two-piece design, providing a larger bearing surface and enhanced lubrication characteristics. Symptoms: Premature wear or bushing failure Insufficient lubrication Cause:Inadequate lubrication or excessive load relative to the available bearing area. Correction:Install the Sonnax one-piece rear case bushing to restore performance, improve durability, and help avoid costly case replacement. Transmissions: 4R100 1998-UP, E4OD 2000 Vehicle FORDE
