I have heard about people doing a transmission change with a vacuum fluid extractor so I purchased one because it sounded easy to do.

Basically I am running the tube down the transmission fill in the engine bay and sucking out the fluid from their. But I am only getting about 2 qts of fluid... I imagine the hose isn't placing in a good spot in the transmission pan..

If I started the truck, wouldn't more fluid circulate into the pan allowing me to extract more of the fluid?

I'm not really going for perfect here. The truck has 68,000 miles of soft use, no towing... So I I probably wont do an oil pan drop/filter exchange until next time...

 

The pan holds about 4 quarts. That vacuum extractor might not be the correct tool for the job. Remove and clean the pan. Reinstall and fill. Disconnect the return tube at radiator or trans and run to pump out the fluid adding as necessary until it is clean, about 8 more quarts. I admit I've never done this and there may be better instructions out there. I just drop the pan, clean, and install a new filter and refill with about 4 quarts every 20k miles.

 

Of course, you can always go to a shop and have it done right with an exchange machine.

 

Doesn't that machine work similar to the manual method of disconnecting the return line and pumping it out?

 

Yes, but fresh fluid is automatically drawn in as the old fluid is pumped out. If you are going to do it yourself, this is the right way to do it, courtesy of Mark Kovalsky:

Being that he was a Ford technician for many many years, I would trust in anything he posts about proper procedural methods.
