How often should the transmission fluid of an Audi A4L be changed?

The replacement cycle for the transmission fluid of an Audi A4L is 60,000 kilometers, with a replacement capacity of 7L. The cycle can be adjusted appropriately based on actual driving conditions. The methods for changing the transmission fluid are as follows: 1. Gravity replacement. After loosening the tightening nut at the bottom of the oil pan, the transmission fluid will automatically flow out from the drain hole. However, not all the transmission fluid can be drained, mainly due to mechanical structures having dead corners such as depressions and pits. 2. Machine circulation replacement. Store the new transmission fluid inside the circulation machine, connect the transmission and the circulation machine through pipeline interfaces, and the new fluid will push out the old fluid under the action of the circulation machine. The more the new transmission is used, the cleaner the oil circuit will be. Changing the transmission fluid once with the circulation machine requires 10 liters of fluid.
My Audi A4L has been running for almost six years, and I’ve done some research on the transmission fluid issue. The maintenance manual recommends changing it around 60,000 kilometers, but in actual use, it also depends on driving habits. For someone like me who frequently drives in the city with constant stop-and-go traffic, it needs to be changed at around 50,000 kilometers. Last time when the fluid was changed, the mechanic mentioned that the fluid was a bit dark, and after the change, the gear shifts felt noticeably smoother. Never delay changing the transmission fluid for too long, as sludge buildup can damage the gears, and repair costs can easily run into tens of thousands. Now, during every maintenance check, I make sure to have the fluid condition inspected—after all, changing the fluid only costs a few thousand, which is much cheaper than repairing the transmission.
