Transmission chatter when cold, but goes away when fully warm

I just recently swapped out my Automatic Transmission in my 91 MR2. The person i received it from had the system completely drained, including the torque converter. I found this out kinda hard the way, knowing that the pan was empty, but not expecting the torque converter to be empty as well.

After filling up the system, i thought i may have overfilled it, because the fluid level was reading above the hot mark on the dipstick. So i drained the fluid and replaced the transmission filter. I put in 3 quarts of fluid and added the 4th quart of fluid over time, mainly letting the car run and warm up to operating temp and then adding fluid and letting it settle. I kept doing this until i got to the full mark on hot.

So this is where im at now…

On a cold start, the transmission will chatter in all gears, from park to low. Give it about minute or so to start warming up the chattering slowly goes away. When its at operating temperature, there is no chattering at all in any of the gears, and it presumes to be normal and fine. It takes about 5 minutes to fully warm up to operating temperature. Should i worry about the chatter at the beginning while its warming up? i have to drive the car because i want to be sure that the transmission is okay. I have thought about adding an additive, but all that i have read is just bad results, and failed transmissions.

Any suggestions?
