賓士原廠技術通報-W204/C300

- No power flow from automatic transmission 722.9 after replacing the hydraulic controller unit -

Topic number	GI27.35-P-020442
Version	2
Design group	27.35 Valve body
Date	03-21-2007
Validity	All models with automatic transmission 722.9
Reason for change	Complaint and validity revised

Complaint

After replacing the hydraulic controller unit on automatic transmission 722.9 (7G-TRONIC), no gear can be engaged in transmission mode "S" and there is no power flow from the transmission. In transmission mode "C" the vehicle starts off as usual (vehicles with gasoline engines only).

Cause

When installing the new hydraulic unit, the supply pipe for multidisk brake B3 was not installed correctly.

File	Designation
Versorgungsrohr.jpg	Supply pipe for multidisk brake B3

Remedy

Remove hydraulic controller unit as described in AR 27.19-P-0200w.

Before reinstalling, install supply pipe as described in AR 27.19-P-0200w, step 6. See also the pictures in the annex.

- Harsh engagement when changing gear range from P to D -

Topic number	GI27.50-P-044018
Version	3
Design group	27.50 Gear assembly
Date	03-11-2010
Validity	Transmission 722.9 up to sequence number 1.842.410
Reason for change	Additional possible remedy

Complaint

When changing gear range from P to D, harsh engagement may be noticeable.

Cause

Friction coefficient fluctuations possible in the B2 disk packs in vehicles with transmission sequence numbers smaller than 1.842.410.

Remedy

Applies only for transmissions with sequence number less than 1.842.410: Replacement of B2 disks. Order parts as per EPC.

Otherwise the engagement sequences for N-D and N-R must be taught in again as follows:

Note: Always remain in the gear ranges N/R/D for at least 5 sec!

Start the engine from cold,

shift 5 times N-R,

shift 5 times N-D --> warm up transmission to 40°C and while doing so, exceed a speed of 50 km/h at least once.

shift 5 times N-R,

shift 5 times N-D --> warm up transmission to 70°C and while doing so, exceed a speed of 50 km/h at least once.

shift 5 times N-R,

shift 5 times N-D.

- Hard 1-2 shift or hard torque converter lockup clutch engagement -

Topic number	GI27.00-P-044014
Version	2
Design group	27.00 General
Date	03-11-2010
Validity	Transmission 722.9
Reason for change	Remedy revised

Complaint

The customer complaint "Hard shift, presumable the 1-2 shift, occurs when moving off" is often received even though the problem is hard engagement of the torque converter lockup clutch (KÜB) in the start-off procedure.

In order to permit a clear diagnosis, restrict the 1st gear before moving off.

If a jolt occurs at the point where the state of the torque converter lockup clutch changes from "open" to "slipping", then the cause should be sought in the control of the torque converter lockup clutch.

Cause

Control of torque converter lockup clutch engagement not ideal.

Remedy

1. Via DAS menu item "Initial startup", perform transmission software update and then perform SCN coding.
   
2. Via DAS menu item "KÜB adaptation", adapt the torque converter lockup clutch according to the coolant temperature and torque window.
   
3. Then perform a test drive.

If the complaint is still present, first work through the diagnosis tree for transmission 722.9 (GI27.00-P-035661) and, if the complaint persists, please contact Technical Product Support and attach a current quick test report and the control unit log to the TIPS case.

- 2-3 upshift slips once -

Topic number	GI27.00-P-046507
Version	6
Design group	27.00 General
Date	08-25-2010
Validity	Transmission 722.9 with engines 273, 272 and 642
Reason for change	Remedy revised; software for OM642 and M272 will only be available for electrohydraulic controller unit 23 06 and 24 06.

Complaint

After a cold start, 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

Topic is known. A software improvement is being produced. Replacing hardware does not remedy the problem.

Software for vehicles with M273 in combination with electrohydraulic controller unit A220 270 23 06 and A220 270 24 06 published with DVD 01/2010

Do not perform any repairs for vehicles with OM642 and M272 until further optimization software is available. Software is being produced for vehicles with electrohydraulic controller unit A220 270 23 06 and A220 270 24 06.
