After changing fluid and filter I added 6 quarts of fluid. I let the transmission warm up and shifted through the gears. I then removed the check plug and added fluid. The car was running in park. I added 2 more quarts and not a drop from the hole. The car was level when I added the fluid. Do I continue to add fluid? Prior to changing the fluid I added fluid to make sure I wasn't low and I did get fluid flow from the hole.
