Beanstandung:

Vehicle jerks during gearchange or has hard or slipping shifts. In some cases the torque converter lockup clutch (KuB) cannot be actuated.

The following fault codes may be stored in the transmission control unit:

2783, 0741, 0894, 0893, 0735, 0734, 0733, 0732, 0731, 0729, 0606, 076F

Affects veh. upto production date 10.01.2011

Ursache:

Torque converter lockup clutch (KuB) cannot be actuated due to a restricted filter in the KuB valve.

Other valve filters, e.g K1 control solenoid valve (Y3/8y2), may also be restricted with wear debris.

Note:

Only replace solenoid valves which can not be cleaned, up to a maximum of 4 solenoids

Abhilfe:

Removal of EHS and removal of all valves from the EHS to evaluate the contamination of the valve filters. Please ob serve AR27.19-P-021 2A.

Install repair filter A 221 277 00 00.

The filter is only valid for NAG2FE+ with OM 642 LS up to transmission sequence no. 3.154.598 and M278 up to transmission sequence no.

3.166.389.

Replacement of the torque converter is not necessary if this repair is

performed

Important:

It must always be ensured that the valves are installed correctly as each valve has a specific characteristic.

The transmission magnets must always be replaced

Finally re-adapt only the specific problem gearshifts.
