Technical issues and repair guidelines

The most widespread malfunctions of MB1:

• Gear fails to switch on. Any malfunction of solenoid-controlled valves of the hydraulic distributor switches the automatic transmission into emergency mode.

• Oil leakages. In many cases car owners are bothered by ATF leakages. Usually the oil leaks at the junction of the motor and the automatic transmission.

• Critical breakdowns. Low oil level and the pressure loss caused by the valve breakdown lead to burn-out of friction plates.

• Shifting failure. A poor valve body breaks before reaching 100 thousand kilometers. This problem has the following symptoms: jerks, kicks and failure of some gears.

According to transmission repair specialists the resource of this transmission is equal to 100 - 150 thousand kilometers, but it is very unlikely that this transmission will cover such distance without any repairs.
