Title: U660E (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: Transmission Control Switch Circuit; 2016 MY Sienna [12/2015 - 08/2016] |
Transmission Control Switch Circuit
|
DESCRIPTION
When the shift lever is in S and it is moved toward "-" or "+", it is possible to select different shift ranges (1st through 6th ranges).
Moving the shift lever toward "+" increases the shift range by one, and moving the shift lever toward "-" decreases the shift range by one.
