Abstract
Abstract An automotive transmission having an hydraulic torque converter and planetary gearing with an output member between the converter and gearing and driven by the gearing, under the control of a compact assembly of axially spaced pairs of radially spaced friction engaging devices, to provide a plurality of forward speed ratios and a reverse speed ratio. This invention relates to transmissions and controls therefor and, more particularly, to change speed transmissions and controls for use in automotive vehicles.

Claim 1
Independent Claim
198 words
In an automotive transmission, a housing, a drive shaft; an input shaft; a hydraulic torque converter in said housing having an impeller connected to and driven by said drive shaft, and a turbine splined to one end of said input shaft; planetary gearing in said housing mounted at the opposite end of said input shaft; said gearing having an output element driven by said gearing; an output gear rotatable on said input shaft connected to said output element to be driven thereby and mounted in a space provided in said housing located between said hydraulic torque converter and said gearing; a governor shaft journaled in said housing parallel to said input shaft and extending through said space; a drive gear drivingly connected to said governor shaft and connected to be driven by said output element of said gearing; said governor shaft and drive gear located radially outwardly of said planetary gearing; a hydraulic governor assembly mounted on said governor shaft in said space and radially outwardly of said output gear and connected to be driven by said drive gear; and said output element of said gearing having external teeth to drive said drive gear on said governor shaft.
