Details and Technology
The fully automated, electrohydraulic, five-speed transmission transfers power to the wheels via a torque
converter with integrated lockup clutch. The lockup clutch minimizes power loss or slip across the torque
converter and can engage in all gears, depending on engine speed and load. This system allows upshifts
to be performed smoothly and almost instantaneously. Selector position P activates a parking lock. This
selector position is the only position in which the ignition key can be released. The selector lever can only
be moved out of position P when the brake pedal is depressed and the ignition switched on. In selector
position D, the transmission always starts in first gear. The transmission control unit subsequently selects
the most appropriate gears automatically, with reference to engine speed and road speed. Upwards of
approximately 4 mph, it is not possible to change from D into R. When the transmission is in automatic
mode (D), it is possible to limit the shift range by nudging the selector lever towards – or + (Auto/Stick
feature). Each time the selector lever is nudged from position D toward –, the shift range is reduced
by one gear, conditions permitting. To prevent excessive engine speeds and maintain the power flow,
downshift requests which would cause the engine to overrev are not carried out. If the selector lever
is pressed towards – and held, the transmission changes down by several gears, conditions permitting.
Each time the selector lever is pressed toward +, the shift range moves up a gear, before finally the
transmission changes to automatic mode (D). If the selector lever is pressed toward + and held, the
transmission changes to automatic mode and shifts accordingly. Ratios: 1st gear, 3.59; 2nd gear, 2.18;
3rd gear, 1.40; 4th gear, 1.00; 5th gear, 0.83; Overall ratio 4.32; Reverse gear 3.16.

high reliability, low maintenance costs.
Remarks
CAUTION:
The parking lock is not an alternative to the parking brake! Therefore, the parking brake
should always be applied when parking.
