Transmission Fluid Level, Checking: Procedure

WARNING: This page is about a different car, the 2015 Audi S7, 2014 Audi S7, and 2013 Audi S7. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

General Repair Instructions, refer to GENERAL REPAIR INFORMATION .

Rules for cleanliness when working on the S tronic transmission, refer to GUIDELINES FOR CLEAN WORKING CONDITIONS .

Do not exchange the transmission (MTF) chamber with the ATF chamber.

The manual transmission, the manual transmission and the transfer case in the S tronic transmission 0B5 share a common transmission (MTF) fluid chamber, which is checked and filled by a single plug.

Gear oil at about 20°C (room temperature).
Move vehicle onto a four-pillar workshop hoist or over a work pit so that it is absolutely horizontal.
The Pressurized Gearbox Oil Filler Kit VAS 6617 must be clean. Flush it with transmission fluid (MTF), if necessary. Do not mix other transmission fluids.
The transmission must be still for at least 15 minutes to make sure the oil settles internally.

-- Remove the rear noise insulation -2-, refer to Noise Insulation .
