ABSTRACT:
A method of shift selection in an electronic automatic transmission wherein a controller is capable of selecting between various desired transmission gear changes or shift patterns to place the transmission in the appropriate gear based on a plurality of input conditions. The method includes comparing a mask with a byte in a table row and determining whether a matching row was found. The method also includes pointing to the next row if a matching row was found and determining whether the present operating gear equals the next byte. The method further includes selecting the next byte to perform a predetermined gear change or selecting another byte to perform another predetermined gear change based on the present operating gear equaling the next byte, and executing the gear change selected.
