Estimating the term…
A family of transmission assemblies is provided that includes both manual and automatic shifting versions. The family utilizes a casing assembly having an interchangeable central housing portion that will receive either a manual or an automatic transmission mechanism. Both the automatic and the manual transmissions utilize an input shaft member, an output shaft member, a countershaft member and a reverse/idler shaft member that are oriented along parallel operating axes and that are disposed in a geometric array which is common to both the automatic and the manual versions. The casing assembly has a central housing portion that has at least a front and rear opening, and a series of supporting axes--one for each of the operating axes defined by the shaft members that are common to both the automatic and the manual versions. The supporting axes are disposed in a geometric array that is congruent to the geometric array of said operating axes.
A casing assembly adapted to receive a vehicular transmission mechanism selected from a family of automatic and manual versions, comprising:
A casing assembly adapted to receive a vehicular transmission mechanism selected from a family of automatic and manual versions having an input shaft member, an output shaft member, a countershaft member and a reverses/idler shaft member that are oriented along parallel operating axes and that are disposed in a geometric array which is common to both the automatic and the manual arrangements, said casing comprising:
A family of transmission assemblies including both manual and automatic shifting arrangements and utilizing a casing assembly having an interchangeable central housing portion and a plurality of common components for both manual and automatic modes of operation, each transmission assembly comprising:
