Bulletin Summary
This bulletin provides information related to a Transmission Control Unit (TCU) software update for certain vehicles equipped with an 8-speed wet dual clutch transmissions (8WDCT) that improves the touch point learning variation. Certain 8WDCTs (indicated by a new part number) received an improved clutch spring. The correct TCU software update must be matched with the correct corresponding 8WDCT hardware, otherwise drivability concerns may occur.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
