Does the Audi A6L require replacing the filter when changing the transmission fluid?
2 Answers
Audi A6L requires replacing the filter when changing the transmission fluid, as changing only the fluid without replacing the filter will shorten the service life of the transmission fluid. The methods for changing the transmission fluid in the Audi A6L are as follows: Unscrew the drain plug at the bottom of the transmission to drain the fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to change the automatic transmission fluid: Dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. The hazards of not changing the transmission fluid for a long time are as follows: Damage to the transmission's shift control mechanism; Abnormal wear of gears and clutch plates inside the transmission; Affects the normal operation of the transmission, leading to damage of the transmission valve body.
As a seasoned driver with ten years of experience behind the wheel of an Audi A6L, I firmly believe that changing the transmission filter is a must when replacing the transmission fluid. The filter is specifically designed inside the transmission to catch metal shavings and impurities, and over time, it can become severely clogged if not replaced. If you only change the fluid without replacing the filter, the new fluid will immediately get contaminated once it circulates, leading to a significant drop in transmission performance—manifested as jerky or rough shifting. From experience, Audi's official maintenance manual recommends replacing the filter at the same interval as the fluid change (typically around 60,000 kilometers). I always replace it during every maintenance session to avoid costly overhauls; a friend of mine once skipped this step, and his transmission developed issues prematurely. In short, it's money well spent to protect your beloved car for long-term use—don't cut corners for the sake of convenience.
