The 2022 Audi Q8 is a great mid-size luxury SUV. The Q8 has a lavish interior with luxurious materials, an elegant dual-screen infotainment system, and ample seating inside both rows. It’s a quiet and comfortable vehicle to drive on a daily basis, but it becomes more lively when the road gets twisty. Around turns, the Q8 has a surefooted feel about it, and each of its turbocharged engine options has plenty of power. Heavier towing capacity and a variety of active safety systems only sweeten the deal for the Q8.

That said, the Q8 has its drawbacks. For this sector, it has an extremely low fuel efficiency, which isn’t exactly a high bar to clear. The Q8 also has a tiny cargo area for a vehicle of its size.

2019 2020 2021 2022 Audi Q8 Transmission Fluid Capacity and Transmission Fluid Type

Transmission Fluid Capacity Fluid Type
0D5 8-speed Automatic Transmission Total Fill 9.1 quarts (8.6 liters)
Initial Fill 3.8 quarts (3.6 liters)

The automatic gearbox in the Audi Q8 is exceptional. They can last a long time without requiring any servicing. However, they require transmission fluid to function. Your Audi Q8’s Transmission fluid will eventually get low over time. The damage has already been done by the time you experience the signs of reduced transmission fluid.

The transmission fluid in your Q8 powers lubricates and cools the gearbox. That’s a lot of pressure for one liquid to deal with.

A transmission that has little or no fluid can be seriously damaged, leaving you stranded. If you believe your transmission is severely low on fluid, you should do everything humanly possible to avoid driving it. Damage will be done significantly rapidly if the transmission begins to slip as a result of a low fluid condition.

Low Transmission Fluid Signs

  • Higher RPM at any given speed – A low transmission fluid level can result in an engine that appears to be revving higher than it should at any particular speed. It could also suggest that the torque converter is not engaging. If it’s the torque converter, though, it’ll only jump a few hundred RPM.
  • Engine sounds different uphill – When you’re going up a steep hill, the fluid may not be able to be picked up from the pan. As the transmission starves for fluid, the engine will accelerate faster.
  • High transmission temperature – The fluid in an automatic gearbox is required for more than just converting mechanical energy to hydraulic energy in the torque converter. It is also necessary for cooling. So, if you have a transmission temperature gauge, beware. Your transmission fluid may be low or empty.
  • Put car into gear, but it’s not going anywhere – If you leave your Q8 unoccupied for an extended period of time, it’s likely to cough up the transmission fluid. So, even if it was full last time you drove your Q8, it may be empty now. You’ll go to use it somewhere and it won’t move at all or barely move. This can frequently be attributed to a loose torque converter. Did you detect any shuddering at highway speeds? That’s an indication that your converter is loose.
