The Mode Select Switch detects the position (the main shift gate side or manual shift gate side) of the selector lever and transmits a manual mode signal or a not manual mode signal to the Combination Meter. Then, the TCM receives a manual mode signal or non-manual mode signal from the Combination Meter.
The Position Select Switch (Up) detects that the selector lever is shifted to the upshift side of the manual shift gate and transmits a manual mode upshift signal to the Combination Meter. Then, the TCM receives a manual mode upshift signal from the Combination Meter.
The Position Select Switch (Down) detects that the selector lever is shifted to the downshift side of the manual shift gate and transmits a manual mode downshift signal to the Combination Meter. Then, the TCM receives a manual mode downshift signal from the Combination Meter.
