2-3 upshift slips slightly one time

Topic number         LI27.00-P-048552

Version               5

Design group          27.00 General

Date                  09-17-2012

Validity              Transmission 722.9 with engines 273, 272 and 642

Reason for change     Model designations with engine 642 and engine 272 for which there is a remedy have been added under Validity

Complaint:

After a cold start, slight slippage may occur in the 2-3 shift when the vehicle moves off for the first time.

Cause:

A full basic charge for the K1 piston cannot be guaranteed with a cold start. This means that the plate contact pressure must still be built up, which

can lead to a single brief slip of the gearshift.

Remedy:

Vehicles with engine 272, engine 273 and engine 642 in combination with the electrohydraulic controller unit A220 270 23 06 or A220 270 24 06 ->

Flash transmission control unit.

Important:

Observe the list in the attachment for vehicles with engine 272 and engine 642 because this software is only available for these model designations.
