Supersedes Technical Service Bulletin Group 38 number 08 - 09 dated November 18, 2008 for reasons listed below.
AFFECTED VEHICLES
CONDITION
No drive, or delayed drive when either D or R is selected. DTC P1743/18151 may be logged in TCM fault memory.
The vehicle does not start moving without accelerating. When accelerating, an increased engine speed is necessary to move the vehicle. In some cases
there is no drive.
TECHNICAL BACKGROUND
Some damaged seals installed in production. The damaged seals may leak after a short operating period (less than 13,000 miles), causing a loss of
transmission oil pressure. This condition will not result in unintentional vehicle movement.
Affected vehicles: Vehicles with Multitronic transmissions produced between May 2005 and May 2006.
PRODUCTION SOLUTION
Improved production.
SERVICE
Tip: It is not necessary to receive an authorization number from the Technical Assistance Center for the repair described in this bulletin.
^ Attach VAS scan tool printouts to the repair order. Warranty requested documents received without VAS scan tool printouts will be denied payment.
^ If fault P1743/18151 (clutch slip monitoring signal too large) is stored in the transmission fault memory, read MVB 44/1 and 45/1. If MVB 44/1 is
1000 mA and MVB 45/1 is above 12 bar, there is a problem with the axial seals. If MVB 45/1 is below 12 bar, this indicates a hydraulic problem.
(See below for further analysis.)
^ If no fault is logged, proceed as follows: With ATF temperature over 90°C (MVB 10 position 3), perform an adaptation drive. (See Guided Fault
Finding for adaptation drive procedure.) Assess the MVB as follows:
