Abstract
A modular transmission housing uses a common front case with a series of rear cases and intermediate bearing support plates. Use of a intermediate bearing support plate permits dividing the main shaft and countershaft into two approximately equal length shafts for a popular seven speed transmission where the rear portion and the front portion of the front and rear shaft portions are supported by bearings in the intermediate bearing support plate. Various transmission sizes such as a five speed, seven speed and ten speed transmission utilizes the common front case for each housing.

A set of interchangeable transmission housings comprising:
- a front case;
- a plurality of differently sized rear cases, each of said plurality of rear cases being adapted to cooperate with said front case to provide a plurality of differently sized models of a basic transmission;
- at least one intermediate bearing support plate, said intermediate bearing support plate being adapted for use with at least one of said plurality of rear cases so as to support shafts within said transmission housing formed thereby;
- and
- means for aligning and securing a selected one of said plurality of rear cases to said front case to form a first transmission housing and an other selected one of said plurality of rear cases to said front case with said intermediate bearing support plate between said front case and said other selected rear case to form a second transmission housing.
