Last week, my 95 accord's tranny fluid was mixed with water because the darn heavy rain over here. Some white/pinky grease formed. It started to slip on first gear if I hold it in D-gear by the traffic light for more than 3 mins. I knew this might be the end of that tranny. So I decided to flush the tranny. Here's how I did it.

1. Bought 14 bottles ATF from Autozone.
2. Detached the pipe from tranny to radiator.
3. Start the engine in Park. Let the pump in the tranny pump all the fluid out while I was pouring all 14 bottles ATF in there. Untill reddish color. This will allow the dirty fluid from torque converter to drain out.
4. Stop the engine, Hook up everything and unplug the drain nut.
5. Drain the remaining fluid from drain hole.
6. Tighten the drain plug and put in appropriate ATF which maintain between the cold line and hot line on the dip stick.

Now it runs great for 3 days, after that it started to form those white-ish and pinky grease again. Gear slipping happened again. My question is,

Is there any other cure to this tranny?
Do I keep on to drain fill the ATF?

Please advice everyone.
Thank you so much and appreciated.
