Gear shifting, N-D and N-R
|
Shifting N-D
When the selector lever is moved from N to D, the transmission will go into 3rd gear for 0.5 seconds so that shifting will be as smooth as possible.
This gear-shifting compensation is carried out on condition that:
1.
|
The brake light switch is activated. Brake lights, ON (bus from TWICE).
|
2.
|
The accelerator is not actuated (throttle closed).
|
3.
|
The shifting program selected is NORMAL or SPORT.
|
Shifting N-D and N-R with accelerator depressed
To reduce wear on the transmission and to minimize jerkiness when R or D is engaged and the accelerator position exceeds 3%, the TCM requests via bus information a reduction in the “maximum permissible torque” during the actual shifting process. The Trionic system uses the information in its air mass control circuit for torque limitation.
