So as I have posted in another thread, my transmission oil is neither black nor red, but is of a milky pinkish color.
This is most likely due to a leak in the radiator between the engine coolant section and the transmission oil section. I have since replaced the radiator, so hopefully no new leaks as of now.

To remove this milky fluid, a flush of the system is needed. However, I am unsure of how to go about this.
The following would be my current idea, up for discussion from you guys:
The oil flows into the transmission from the lower hose on the radiator and out through the upper hose. I am planning on extending those hoses and simply stick the upper hose in my waste oil container and stick the lower hose into my fresh oil. I could then simply turn on the car, switch through the gears and wait until the fluid spewing into the waste oil container turns clear.
Would that be a feasible option or do I need some external pressure to push the fluid through the transmission and converter? Will I get rid of all the contaminated fluid this way?

Thanks for your inputs!

Drain transmission and converter. Disconnect the front cooler hoses at the transmission and blow compressed air through the hoses.

Fill and run.

Repeat until all traces of water are gone....although you probably will not have to blow through the hoses a second time.

What Greg said. Pushing fluid back into the trans from the cooler end will work fine, but doing that offers no way to remove the contaminated fluid from the gearbox. For that you'll be draining and filling a couple times as he recommends. Blow through the cooler itself with air to make sure there isn't a slug of contaminated fluid waiting to go back through when you restart.

Torque converter has it's own drain plug on these cars, just in case you didn't know.
