ATS Billet Reverse Servo Piston Kit (Low Reverse Accumulator) for Dodge (1996-07.5) 2500/3500 5.9L Cummins 47RE/48RE

This full billet, redesigned servo corrects the problem with the weak factory cast design. It has a wide Viton wear ring that prevents the servo from scoring onto the cast aluminum transmission case when applied. The large ring also insures the servo stays centered in the bore providing a perfect hydraulic seal every time it is applied. This is the servo that is located at the back of the transmission inside the pan. This part can be replaced and upgraded without removing the transmission.
