Shifting N-D
When changing the selector lever position from N to D, the transmission will temporarily shift to 3rd gear so that shifting is performed as smoothly as possible.
This gear-shifting compensation is carried out on condition that:
|
1.
|
Brake light switch is activated. Brake lights, ON (bus from TWICE).
|
|
2.
|
Accelerator pedal not depressed.
|
|
3.
|
The shifting program selected is NORMAL or SPORT.
|
To reduce transmission wear and to obtain smoother shifting when R or D is engaged when the accelerator pedal position is greater than 3 %, TCM requests a lower “maximum permitted torque” at the moment of shifting over the bus. Trionic uses this information in the mass air flow control circuit for torque limitation.
