Trans fluid complete change

I have a 2013 4x4 with trailer package. Inside this forum is a great write up regarding an almost complete trans fluid change by disconnecting the trans cooler line and draining the fluid by starting the engine - drain a few quarts, shut down - refill, repeat, repeat, repeat. Doing this alone isn't going to be possible.
My question to those that "Know" , could a fluid pump (suction side) be used on the trans cooler line to "draw" the fluid out in a more controlled fashion? This would /may also result in more fluid being taken out at a single time since no engine power is used. It further would facilitate greater accuracy and control in measuring of how much was removed and then replaced. Yes, It may take quite a bit longer time wise,
Just brainstorming.

 

?? I did mine by myself. Just have to know you don't want to drain more than 3 quarts total at a time. To be safe I drained 2 quarts =/- each time. Just takes more time. Get in - foot on brake - cycle through the gears - put it in park and turn it off - go check how much came out and adjust cycle time accordingly. Start with 10 seconds of time and see what came out. GL.

 

goldenbrew, You have much more talent than I. I will be cleaning qrts of fluid from the floor.

If you have access to a air compressor use a fluid evacuator. Might need to get a longer line though.

 

I wouldn't drain a transmission like this. Drop the pan and just accept what's left is staying unless you want to drain a few times
