Technical Bulletin #1687Transmission:Subject:Application:Issue Date:09GMissing B1 Clutch Housing Retaining Snap RingVWJune, 201509GMissing B1 Clutch Housing Retaining Snap RingIn the past there have been a number of inquiries concerning a missing B1 clutch housing retainingsnap ring in various Volkswagen models equipped with the 09G transaxle. We have seen a number ofthese vehicles in shops where upon disassembly there is no B1 clutch housing retaining snap ring.Upon closer inspection of the B1 clutch housing setup, the technician will notice the snap ring doesnot effectively retain the B1 clutch housing in the transmission, and is not necessary for normal operation. A good rule of thumb is to reuse the snap ring if it was installed in the transmission and foundduring disassembly and to leave it out if there was no snap ring installed. Refer to the figure below foridentification and location of the B1 clutch housing retaining snap ring.Copyright 2015 ATRA All Rights ReservedDC Page 1 of 1
