 There are transmission operation issues due to the lack of oil.
Workshop findings:
 ATF leaking from the service opening of the lower bellhousing.

Technical Background
Leaking through the bolt holes of the clutch cover.

Production Solution
Not applicable.

Service
Make sure that the oil leak definitely occurs in the bellhousing (clean transmission and apply talcum spray/leak
detection spray to locate the concern on the service opening of the bellhousing).
If the oil leak is limited to the service opening in the bellhousing:
 Remove the transmission according to the repair manual.
 Remove the dual-mass flywheel from the bellhousing according to the repair manual.
 After removing the dual-mass flywheel clean the transmission housing and locate with talcum spray/leak
detection spray the oil leak location on the clutch cover.
If the leak cannot be precisely located with the previous check, perform the following steps:
1. Remove the lower bolt of the cover on the passenger’s
side of the plastic cover (Figure 1 and Figure 2).
