I killed my first trans pump

maybe he only had 8qts in it .
Started out with 2 in the converter, 2 in the pan, then instantly added a good 8 or more after start up. After pulling the trans back out, and putting all that fluid in a 5 gallon bucket, it filled halfway around 2.5 gallons...theres still some in the converter.
Valve body yielded about a pint after opening it up...its all contaminated lol..killed it man..
So where I'm at right now. 1 brand new rebuilt Keith Long trans, 1 brand new Torque converter going in instead. Ill just scrap the idea of saving this one. Thanks for everyones input...much appreciated.
