Abstract:
1. A transmission servo rod receivable by a transmission-housing bore, the rod comprising: an aperture disposed along an exterior surface of the rod configured to receive transmission fluid from a port within the transmission housing bore; a first recessed groove in the exterior surface of the rod disposed above the aperture; a second recessed groove in the exterior surface of the rod disposed below the aperture; first and second resilient sealing members received within the first and second recessed grooves, respectively, the first and second resilient sealing members configured to engage an inner surface of the transmission housing bore; and an assembly sleeve surrounding a portion of the exterior surface of the rod above the first recessed groove, wherein the assembly sleeve comprises an external chamfer on an external diameter on one end of the assembly sleeve and an internal chamfer on an internal diameter on the opposite end of the assembly sleeve, wherein the internal chamfer is operable to resize at least one of the first and second resilient sealing members upon installation onto the rod, and wherein the first and second resilient sealing members are configured to predominately provide a fluid seal for a non-symmetrical wear of the transmission housing bore.
