how much merc V for a trans fluid change?

going to do my filter and fluid in a couple of days, but needed to know how much I need to have on hand and how much to expect to catch.

the proper way to drain a ford transmission and get 98% or the fluid out is to un-hook one of the trans lines, put a hose on both ends and place them in a drain pan or 5 gallon bucket then thart the engine, leave it in park and let it run untill no more fluid comes out.

then you will need 9-10 quarts, plus when you pull the pan you wont make as big of a mess.

Not a good idea. Once the sump is dry there is no more lubrication for the transmission.


A better way is to pour fluid in as it comes out. Put in about 12 quarts then reinstall the line and top off as needed.

FYI, the trans will pump about a quart every 30 seconds at 1000 rpm.

this is how ford says to drain the transmission.

I thought you were describing the drive way fluid flush method. Your step by step is a tad confusing. Changing the filter then draining the trans threw me for a loop.

I agree, bad idea!!!!! I pump a gallon out at a time, replacing with a gallon of new Mercon V each time. After pumping out the 4th gallon, I drop the pan, replace the filter, and reinstall the pan before replacing the 4th gallon.

Without a doubt, you are a legend in your own mind!!!

I'm glad you think so highly of yourself......too bad nobody else thinks so!!

And, for your information, Ford (or any other vehicle manufacturer) does not recommend pumping a tranny dry!! The recommended equipment, and procedure pumps fresh ATF in, as the old ATF is pumped out!!

Name calling, WOW.

My A&P trumps your ASE. On a side note, your grammar is that of a 12 year old.


Obliviously there is more than one way to skin a cat. The mature route is the way things should be done. There is no need for bickering when theres a difference of opinion. It makes everyone involved look like a bleeding vagina.

People disagree with you on this method. You say this is the way ford trained you. Well Ford isn't the king of maintenance, they do things for different reasons. Some to save the tech time, some to cost the customer money.

IMHO, running any lubrication system dry for any reason is asking for trouble.

I will second this, i just checked my ford service manual-one you will find in the shops office-and it states a similar method, disconnect a line, put a hose on each end and run for 5 minutes to circuate all the fluid
I would scan the picture but the scanner isnt working and print is to small to take a decent picture to post, but this guy may know what hes talking about after all

hmmm, the picture Blhde posted does not state to pump the tranny dry, it states to pull the bolts and let the fluid drain out of the pan. I'm curious to see what the link in number 6 refers to.

In "04 Edge"'s procedure, he isn't circulating the ATF, he is pumping it out of the tranny!!! You need the machine (described in my previous post) to replace the ATF as the old ATF is being removed.......

I was assuming that when he said he was running till atf was out i thought this was the procedure he was using untill all the atf was out, not literally running all the atf out
I guess that whole never assume statement got me again
