Transmission Fluid, Draining And Filling: Draining

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 .

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.

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

-- Place the Used Oil Collection and Extraction Unit SMN 372500 under the transmission.

WARNING:

Danger of eye injury.

Wear protective eyewear.

NOTE:

Place a cloth over the tunnel crossmember to prevent transmission fluid (MTF) from getting into the cast pockets on the top.

In the following description, vehicles with drain plugs for transmission fluid (MTF) are differentiated from vehicles with Transmission Fluid Temperature Sensor 2 -G754- in place of drain plugs for transmission fluid (MTF).

-- Place a cloth over the tunnel crossmember.

NOTE: The drain plug for the transmission fluid is located behind the transmission fluid pan.

-- Remove the transmission fluid (MFT) drain plug -arrow- on the bottom of the transmission housing.

-- Drain the transmission fluid (MTF).

-- Tighten the transmission fluid drain plug (MTF) -arrow-.

Vehicles with Transmission Fluid Temperature Sensor 2 -G754- -1- instead of a transmission fluid (MTF) drain plug:

-- Turn off the ignition.

NOTE: The connector on the Transmission Fluid Temperature Sensor 2 -G754- can be disconnected only when the ignition is turned off. The transmission will switch to emergency mode if the ignition is on. The counter for the increased temperature will count up and a DTC memory entry will be stored in the Transmission Control Module -J217- after 10 minutes.

-- Disconnect the connector -2- from Transmission Fluid Temperature Sensor 2 -G754- and tie it up.

NOTE: Protect the connector -2- and the contacts on Transmission Fluid Temperature Sensor 2 -G754- from transmission fluid. Clean the connectors immediately if they come in contact with transmission fluid (Manual Transmission Fluid). Transmission fluid can cause contact problems in the connector contacts.

-- Remove the Transmission Fluid Temperature Sensor 2 -G754- -1-.

-- Drain the transmission fluid (MTF).

-- Tighten the Transmission Fluid Temperature Sensor 2 -G754- -1- and connect the connector -2-.

Tightening Specification: Transmission Fluid Temperature Sensor 2 -G754- to transmission, 45 Nm

All vehicles:

CAUTION:

Danger of causing damage to the transmission.

If there is no transmission fluid in the transmission or if there is insufficient transmission fluid (Manual Transmission Fluid) in the transmission,

do not start the engine and
do not tow the vehicle
