Gather your materials: You will need new transmission fluid, a drain pan, a funnel, and a wrench set.
Prepare the vehicle: Lift the vehicle and secure it on jack stands. Make sure the engine and transmission are cool to the touch.
Locate the drain plug: The drain plug is located on the bottom of the transmission pan.
Drain the old fluid: Place the drain pan under the drain plug and loosen the plug with a wrench. Allow all of the old transmission fluid to drain into the pan.
Replace the drain plug: Once all of the fluid has drained, reinstall the drain plug and tighten it securely.
Add new fluid: Use a funnel to add new transmission fluid to the transmission through the fill plug. Refer to your owner's manual for the correct amount of fluid.
Check the fluid level: Use a dipstick to check the transmission fluid level. The fluid level should be between the "full" and "add" marks on the dipstick.
Test the transmission: Start the vehicle and let it run for a few minutes. Shift through all of the gears and check for any 異常 noise or vibration.
It's important to note that the exact steps for changing the transmission fluid may vary depending on the model and year of your Audi. If you are unsure about how to perform this maintenance, it's best to consult your owner's manual or a qualified mechanic.
