Electronic Shift for Automatic Transmissions (ESAT) 900560

The object of this paper titled “Electronic Shift for Automatic Transmissions” (ESAT), is to describe the latest developments in remote vehicle shifting systems or shift-by-wire for passenger vehicles and light trucks. Also, included in this paper is a description of the system, hardware and software development, testing and vehicle installations.
The ESAT system, with its 2 or 3 module concept, provides packaging flexibility and offers the interior designer complete freedom for ergonomic styling. The system prevents the occurrence of shift linkage “PRNDL” misalignment in that it is pre-adjusted. It also improves transmission reliability by providing enhanced features such as; ‘automatic cycle to park’, ‘shift lock’, and ‘speed lockouts’.
