Did you drain or pressure flush the torque converter? If not, it still held about a gallon of contaminated fluid..............

Just draining the fluid leaves a huge quantity of contaminated fluid still in the torque converter and front pump; this stuff will not come out with just a "gravity" drain, it needs to be pushed out.
Unfortunately, that means taking the car to a shop equipped with a powered fluid exchange unit (costs about $2,000 for the unit, so this is not a DIY project) that uses a pump to push fluid under pressure through the entire unit, cleaning everything out. The only other way to do it is to pull the transmission and disassemble it. The only possible place coolant can mix with trans fluid is in the transmission cooler.
