A dry 4L60E with a new 12" converter will hold between 12-13 quarts of fluid, on average. Certain things will change this figure. If you add an auxillary cooler, it will take more. If you use a smaller diameter converter, it will take less. A 4L60E will take 4-6 quarts on a fluid and filter change. These figures depend on how much it has drained down, how long it's been sitting, and the pan depth.
Many people ask about the proper fill procedure for a freshly built trans. Some prefer to pre fill their torque converters. There's nothing wrong with that, but it can make the job a little more messy while trying to install it. It's OK to install the converter dry as long as you follow a specific fill procedure. This is how I was taught 24 years ago, and it always works. Get everything bolted in and then dump 4 quarts down the dipstick tube. After that initial 4 quarts, start the engine for 3 seconds and then shut it off. Then dump another 4 quarts in it and start the engine again. You can leave the engine running and add fluid until you get the correct reading on the dipstick. If you try putting that initial 8 quarts in without starting the engine after the first 4, it will most likely puke fluid out the vent/overflow.
