General information
The transmission operates without interruption of the propulsive force, a main disadvantage of automated manual transmissions. Even compared with the most modern automatic transmissions, its higher efficiency is clearly noticeable.
The requirement profile for the transmission has been designed for 'comfort' and 'functionality'.
As with conventional manual transmissions, the gear ratios are accommodated inside the transmission in the form of gear pairs on input and output shafts.
The input shaft is split into two parts and comprises the hollow shaft and the core shaft.
The dry clutches, which are electronically controlled and mechanically actuated on this transmission, have been arranged in a parallel layout in order to save space. This has achieved a compact transmission design.
The external gearshift mechanism has been carried over from the automatic transmissions.
The Select Shift ™ selector lever has the following positions:
- P : Park position
- R : Reverse gear
- N : Neutral position
- D : Automatic shifting of all gears
- S : Sports mode and manual shifting (Select-Shift mode)
The O/D selector lever has the following positions:
- P : Park position
- R : Reverse gear
- N : Neutral position
- D : Automatic shifting of all gears (with O/D cancel)
- L (Low): Low mode
If the selector lever is in the position P , then 1st gear and reverse gear are engaged via the TCM.
This results in a faster response after the starting process.
The main features of this transmission are:
- Front transverse installation
- Two-part aluminum housing
- 6 gears plus reverse gear
- Dry clutch with travel-controlled wear adjustment
- Two-part input shaft
- Two output shafts with different transmission ratios for the final drive
- Electro-mechanically actuated clutch and gearshift system
- Suitable for use in hybrid vehicles
