Transmission Control Switch Circuit |
DESCRIPTION
When the shift lever is in S and moved toward "-" or "+", it is possible to select different shift ranges (S1 to S8).
Moving the shift lever toward "+" increases the shift range by one, and moving the shift lever toward "-" decreases the shift range by one.
