Bushwhacked! Keys to Avoiding Preventable Bushing Problems
Brian Wing
Package Quantity: 4
The OE rear case bushings in Ford E4OD and 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 rear case bushing 36008B or 36008D using the Sonnax installation tool T36008A to draw the replacement bushing into place. 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.
