O-Rings, Shaft Seals, Seals

WARNING: This page is about a different car, the 2014 Audi A5, 2013 Audi A5, 2012 Audi A5, and 2011 Audi A5. However, it is still accessible from the selected car via links, so may be relevant.

O-rings, shaft seals and seals must be replaced.
After removing gaskets, examine contact surface on housing/shaft for burr resulting from removal or for other signs of damage.
Thoroughly clean housing joint surfaces before assembling.
To install, thinly coat shaft seals along outer circumference and on sealing lip with ATF.
Coat O-rings with ATF before inserting to prevent crushing rings during installation.
Always only use approved ATF. Other lubricants will cause the transmission to malfunction.
The open side on the shaft seals faces the fluid to be sealed off.
Press in new shaft seal, so that the sealing lip does not run on the same point as the sealing lip of the old shaft seal (use insertion depth tolerances).
After installing, the following fluid levels must be checked and topped off if necessary. Refer to ATF LEVEL, CHECKING and GEAR OIL, CHECKING LEVEL . Capacities (Refer to CAPACITIES ), Specifications.
