Abstract
Official abstract text for this publication.
A shift by wire control for a multi-speed vehicle transmission is provided. The control includes a shift by wire shift valve in fluid communication with other shift valves and clutch trim valves to provide double blocking features in the neutral range and a reverse range. The shift by wire valve is configured with multiple differential areas to provide failure modes for all forward ranges.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of operating a transmission, the method comprising receiving one or more electrical shift request signals by an electrical control of the transmission to shift the transmission to any one of a plurality of forward ranges from a non-forward range, and shifting the transmission from the non-forward range to the any one of the plurality of forward ranges in response to receiving the one or more electrical shift request signals by actuating at l…
