How much transmission fluid does my C3 need?

You should read the owner's manual of your C3 to know this information.

If this information is not stated in the manual, you can discard the used oil and fill the same amount of oil that you just took out of the transmission. The downside is that you will not be able to use your car to go buy the fluid you need.

It is essential that your car is in good condition, so you can read the following guides to find out how often you need to change this fluid to ensure its good performance.
