I have a C6 A4 auto and was wondering if anyone has used sealer between trans and diff to make sure there is no leaking between diff and trans. Not on the rubber seal but on the case surfaces between trans and diff. The service manual does not say anything about using any. Seams like like a little sealer would be a good idea. Could it hurt. Also what kind of sealer would you use.
