Audi A4 Manual Transmission Fluid Change B8 Chassis

This article will provide the necessary steps and information on how to change the manual transmission fluid on a 2009-2016 Audi A4 Quattro. The 2009-2016 Audi A4 Quattro was optioned with two types of 6-speed manual transmissions. These transmissions are referenced or identified as a 0B2 or 0B4 manual transmission. These are the first three letters of the transmissions part number. In this article we will also provide the information to the following questions: What type of manual transmission fluid (MTF) should be use? What are the necessary tools needed for changing the MTF transmission fluid and what are the fluid filling capacities for these manual transmissions? 

Although this procedure is demonstrated on a 2012 Audi A4 6-speed manual transmission, the procedures will also apply to other Audi models that came equipped with the same 0B2 and 0B4 type 6-Speed manual transmission. Mild differences due to exhaust down pipe placement will result in the fill plug on the side of the transmission being slightly harder to access.

Always refer to the owner's manual and factory service manual for Audi manual transmission fluid changing procedures.

How To Step 1

Since the manual transmission fluid gear oil is a thicker viscosity it is best to get the transmission fluid warm before draining it. This can be done by taking your car for a quick 10-15 minute drive. This will allow the viscosity of the manual transmission fluid to thin and flow more easily from the transmission.

How To Step 2

Lift the vehicle using an approved automotive hoist or a floor jack and jacks stands so that the vehicle is in a perfectly level position. To confirm you are lifting the vehicle correctly reference your factory owner’s manual for the proper vehicle lift point locations and procedures. The vehicle needs to be in a level position to confirm the correct manual transmission fluid level when refilling. If the vehicle is not level this can cause the manual transmission fluid level to be incorrect and could cause transmission damage.

How To Step 3

Using you T-25 torx bit and a regular screwdriver, remove the six T-25 torx and two plastic push rivet fasteners holding the rear portion of the under engine protective plash pan in place.

Note: This is a two-piece splash pan. The front portion of the splash pan can remain on the vehicle while the manual transmission fluid is being changes. However, for more working area it is optional to remove the front portion of the under engine protective splash. Unfortunately, this vehicle was not equipped with the under engine protective splash pan. This is the reason for no images.

How To Step 4

Important Note: This is an optional step. It is possible to remove the manual transmission drain plug without removing the suspension subframe support X-brace. However, clearance is minimal in the area. As illustrated, we did perform this service without removing the suspension subframe support X-brace.

Remove the suspension subframe support X-brace and place it off to the side. This is held in place by four 18mm hex head bolts and two 14mm triple square bit type bolts. (Image 1)

Important Note: firmly secure the suspension subframe support X-brace with one hand while removing to confirm your do not drop it on your head!

How To Step 5

Using a 10mm hex bit loosen the manual transmission fill plug. (Image 2 and 3)

Always remove the fill plug first when servicing transmissions. This confirms you have a way to fill the transmission with new MTF fluid before draining the old fluid. I've occasionally seen scenarios where the fill plug was seized and couldn’t be removed.

Thorley clean the drain plug. Typically, its normal for a small to medium amount of metal has been attracted to the magnetic drain plug. (Image 7)

How To Step 8

Once the old manual transmission fluid has been drained from the transmission reinstall the drain plug and torque it to 32 lb. ft. (Image 8)

Note: The Audi 0B2 manual transmission drain plug is not equipped with any sealing washers. The drain plug relies on a slight tapered thread to confirm a good seal. Confirm the drain plug area and drain plug threads are clean of all debris and oils. This will help ensure a good seal.

How To Step 9

With the vehicle in a level position begin filling the manual transmission with fluid. Confirm your using the correct manual transmission fluid specification as specified above. (Image 9)

The Audi 0B2 manual transmission fluid capacity is 4.5 liters. The Audi 0B4 manual transmisison fluid capacity is 3.8 liters. Allow the transmission to fill with fluid until it overflows from the fill plug port. Allow 5 minutes to pass. This will allow any trapped air to escape from the transmission.

Allow a few last ounces of manual transmission fluid to flow into the transmission. Once the fluid has overflowed a second time from the fill plug port re-install the fill plug and torque it to 32 lb. ft. (Image 10 and 11)

How To Step 10

Using a rag, thoroughly clean the drain and fill plug area of all oil residue and overflow.

How To Step 11

As mentioned in step 4. If you did remove the suspension subframe support X-brace in order to gain access to the drain plug, you will want to reinstall it at this time. (Image 12)

Important Note: firmly secure the suspension subframe support X-brace with one hand while installing to confirm your do not drop it on your head!

How To Step 12

If you did lift the vehicle with an approved automotive hoist or floor jack and jack stands you can lower the vehicle as highlighted and referenced in your factory owner’s manual. Confirm the correct vehicle lift point locations and procedures as highlighted in your factory owner's manual.

How To Step 13
