ABSTRACT:
A compact change speed transmission comprising two planetary gear sets which are selectively controlled by clutches and brakes to provide four forward speed ratios and a reverse speed ratio. There are a forward clutch, a forward one-way clutch, and a low one-way clutch which, when the forward clutch is engaged, provide a path of transmission of reaction to a stationary part thereby establishing a path of transmission of torque through at least a part of two planetary gear sets to establish a predetermined one forward speed ratio. A low and reverse brake and an overrun clutch are provided. When both of them are engaged, they hinder the action of the low one-way clutch and that of the forward one-way clutch thereby providing engine braking during running with the predetermined one forward speed ratio. For compact arrangement, the overrun clutch is disposed within a clutch drum of the forward clutch with its actuating piston slidably received by an actuating piston of the forward clutch.
