Automatic, planetary, four-speed transmission with a torque converter of the company ?�Mercedes-Benz?�

Lever

The lever has six positions:

• P - Parking
• R - Reverse
• N - neutral
• D - Automatic inclusion of all forward gears
• 3 - switch I, II and III programs
• 2 - switch I and II programs

* Automatic transmission for vehicles manufactured after 1980
** An automatic transmission is available in two variants of gear ratios.

Due to a malfunction of an automatic transmission are almost always low urovenmasla or improper adjustment of the selector or thrust enable low gear.

The oil level, if it has a temperature of about 80 ?� C, should be near the mark "MAX" on the dipstick. When the oil temperature between 20 ?� -30 ?� C level should be at the level of ?�X?� on the mark ?�MIN?�.
