How To Step 18

With the vehicle in a level and elevated position start filling around 2.5 liters of ATF into the transmission. This can be done by gravity or a pump. A pump is a quicker option.

  • With the 2.5 liters of ATF in the vehicle and the fill adapter and hose still attached to the transmission pan. Start the vehicle's engine.
  • With the brakes applied, shift/select through all the gears of the transmission while the engine is idling. Allow 3-5 seconds for each gear selection.
  • With the transmission back in park and the engine still at idling, continue to gravity feed or pump the remaining 2-3 liters of new ATF into the transmission.
  • Once all 5.5 - 6 liters have been pumped into the transmission and the engine is still at idle quickly remove the fill adapter tool, and install the drain plug. Tighten the drain plug enough to minimize a leak.

Why do we supply 6 liters of ATF in this transmission service kit?

We supply 6 liters of ATF for this application to ensure all customers have an adequate amount of ATF on hand for all ATF-changing scenarios.

Typically draining the transmission fluid, lowering the transmission pan, and replacing the transmission filter will allow around 5 - 6 liters to drain from the transmission. The remaining 1 - 2 liters are in the torque converter, transmission cooler lines, and transmission cooler. Some customers allow a longer duration (siting overnight) to pass while changing the transmission filter and ATF. At times this allows another 0.5 - 1 liter to drain from random internal areas of the transmission. Others choose to drain the ATF during excessive transmission temperatures, loosen transmission cooler lines to remove more ATF from the transmission cooler-related areas, and other alternative techniques.

Our kit contains 6 liters of ATF for all average ATF fluid and filter change situations. This provides most customers an adequate amount of ATF while filling and fluid level checking the transmission. We also recommend having an extra liter in case a customer spills and would not typically have enough ATF on hand to complete the service.

Also, many individuals and automotive service facilities choose to drain the ATF into a measuring pan and will only pump the same amount of ATF back into the transmission as was removed. This is not the correct filling process and will yield an incorrect fluid level. We encourage all to use the recommended transmission fluid temperature leveling sequence. Bringing the ATF along with the transmission up to operating temperature together from cold allows for the most accurate ATF level and transmission shifting characteristics.

If you desire a more thorough ATF flush, we recommend driving the vehicle for 5-10 minutes and then performing a 2nd ATF drain, fill, and ATF leveling procedure with another 4 liters of ATF. This should allow the majority of harshly contaminated ATF to be removed from the transmission.

(To allow for a quicker flow of ATF into the transmission you may use ATF pump tool number J91001 as described below.)

To allow for a quick flow of Audi ATF into the transmission you can use pump tool number J91001. See our J91001 Instructional Document that shows how to adapt the pump to the Ravenol bottle spout tube. The hand pump base can be adapted directly to the Ravenol bottle tube that pulls out from the Ravenol bottle cap. As the fluid is pumped into the transmission, the bottle will collapse as the fluid is sucked from it. This may not be the prettiest way to pump fluid into the transmission, but it is an adequate and cost-effective way to fill the fluid, rather than having to buy the more expensive T2A0152 tank and T2A0108 adapter.Audi Transmission Fluid Change on Q3 TT Aisin Transmission How To Image 28

How To Step 20

With the vehicle level, and the engine still at idle. Bring the transmission fluid temperature to warm between 35°C - 45C° (95°F –113°F). During this process and as you wait for the transmission fluid temperature to rise, you can remove the transmission drain plug and transmission fluid should begin to flow out from the fill port level insert. When this happens, the proper ATF fluid level is transitioning to the correct level. The ATF fluid level is correct when the transmission fluid transitions from a consistent stream into its very first drip between the fluid temps of 35°C - 45C° (95°F –113°F).

Side Note: Do not allow the transmission temperature to exceed 45C° (113°F). Reinstall the 14mm hex bit drain plug before the transmission fluid temperature exceeds 45C° (113°F).

Side Note: If no fluid drips from the fill port between the temperatures of 35°C - 45C° (95°F – 113°F), the proper level has not been achieved. Reinstall the 14mm hex bit drain plug, turn off the engine, and allow the transmission to cool to below 30°C (86°F). Repeat the transmission fluid level process per the above-recommended steps 19 - 20. An additional 1 or 2 liters of ATF may be required to re-perform the overflow fluid level check.

It’s also important to note that the above ATF level process must be done quickly before the transmission exceeds 45C° (113°F).

How To Step 21

Reinstall the 5mm Allen drain plug and torque to 12 ft. lbs.

How To Step 22

Once the proper Audi Q3 or TT transmission fluid level has been attained, turn the engine off and exit the Ross-Tech diagnostic software and disconnect the OBD2 plug port.

How To Step 23

If you do not have a Ross-Tech diagnostic software available to you for reading the internal transmission fluid temperature you can use any diagnostic software that can access and read the internal transmission fluid temperature. The most accurate transmission fluid level and temperature reading is achieved using diagnostic software.

However, if you do not have diagnostic software, you may wish to use other options to read the transmission fluid temperature. One alternative is an infrared thermometer - See Image. Typically, an infrared thermometer reads within a 4° to 5° degree difference when compared to diagnostic software which measure the true internal transmission fluid temperature. Thus, an infrared thermometer can be a reliable temperature source when performing the transmission fluid leveling sequence. If an infrared thermometer is used it is best to allow the fluid temperature and level reading to be more towards the low side of the temperature window of 35°C - 45C° (95°F –113°F). For example, a 34°C reading will be closer to a 38-39°C internal fluid temperature reading.
