The OE rear case bushings in the Ford E4OD and 4R100 & C6 transmissions tend to wear out prematurely. Bushing failure may be due to lack of lubrication, excessive journal clearance, or too much load for a given bearing area. Replace the two OE bushings with Sonnax replacement bushing 36008B or 36008D using the Sonnax installation tool T36008A to draw the replacement bushing into place.

  • Available for both 3-groove early design style and 4-groove late model designs.
  • Both one-piece replacement bushings are an improvement over the OE two-bushing design because of their increased bearing surface area and superior lubrication characteristics.

On some C6 applications there may be a ridge of unmachined material which separate the two OE bushings. This area must be honed down to allow installation
