ABSTRACT:
A transmission includes a transmission case, which defines a generally cylindrical bore that is sufficiently configured to pilot a fastening block member therein. A generally annular groove is defined by the transmission case and is sufficiently dimensioned to receive a snap ring. The snap ring operates to limit the axial movement of the fastening block member with respect to the generally cylindrical bore. An extension housing having a hub portion is also provided. A flange portion extends generally radially outward from the hub portion. The flange portion defines at least one bore that is sufficiently configured to receive a threaded fastener. Similarly, the fastening block defines at least one threaded bore sufficiently axially aligned and configured such that the fastener can threadingly engage the fastening block to secure the extension housing with respect to the case.
